Template:Disambiguate The Enterprise races against Romulans to make first contact with a powerful entity code-named "Tin Man."
As an initial step in the process surveying systems for Federation colonization, the USS Enterprise-D is on routine assignment preparing detailed exospheric charts of the Hayashi system, when the USS Hood is detected on long-range sensors rapidly approaching on an intercept course. Captain Robert DeSoto of the Hood, a long-time friend of Captain Picard, as well as Commander Riker's former captain, hails the Enterprise on a secure channel to inform them that while new priority orders from Starfleet Command are time-critical, because of security concerns of Romulan subspace surveillance the orders are being conveyed to the Enterprise via mission specialist Tam Elbrun.
The fact that this new mission is being spearheaded by Tam Elbrun causes concern among many of the command personnel of the Enterprise, particularly Commander William T. Riker due to Tam Elbrun's involvement in the Ghorusda Disaster, which had cost the lives of forty-seven Starfleet personnel, among them Captain Darson of the USS Adelphi and two of Riker's Academy classmates. Many people, including Riker, blame Tam Elbrun for this tragedy.
Ship's counselor Deanna Troi asks the captain if she may come with him to greet Tam, and discloses that she had previously known Tam Elbrun as a patient at the university on Betazed where she was studying psychology.
Picard is informed by Troi that Tam is considered a gifted telepath, even by Betazoid standards, and is a specialist for Starfleet in First Contact situations. Lt. Commander Data and Captain Picard greet Tam in the transporter room where he is beamed over from the Hood by transporter chief Miles O'Brien. Though Picard extends common courtesy in welcoming Tam to the Enterprise, Tam appears almost brusque and aloof towards him, and causally attempts to forestall what Tam considers uncomfortable extended interaction with others by tossing his orders, and mission details, to Picard on an isolinear data chip. Tam's attitude change is noticeably visible as he turns to greet Deanna Troi, with whom he has a more friendly and more comfortable relationship. He is however startled when Data interjects his welcome, questioning who or what Data is. Data explains that he's an android. Tam is interested, since he cannot "read" Data's presence at all via his telepathic senses; it's as if Data's not there.
Tam launches into a quick recitation to Data of Picard's wishes and orders for Data, by reading Picard's thoughts and cutting off Picard's spoken orders. It is not known whether this is once again to simply expedite his being around Human members of the Enterprise's crew, a demonstration to Picard of his own prowess as a telepath, or a combination of the two. It does however noticeably annoy Picard as he confirms what Tam had stated to both Data and via intercom to Riker on the bridge that course heading and basic mission orders are being brought to the bridge, and that a staff bridge briefing would occur within fifteen minutes. Tam expresses his desire to quickly complete the briefing so he can seclude himself as soon as possible until he is needed further.
As the bridge crew assembles to first review the orders on the supplied chip, then for the staff briefing on the new mission, Riker tells Lieutenant Commander Geordi La Forge in the turbolift more background on the Ghorusda Disaster than what La Forge knew from common knowledge, and how Tam Elbrun, while not officially found to be responsible by a Starfleet Board of inquiry, should have been more competent and aware in order to prevent such an incident.
The new mission orders are that the Enterprise is to proceed to the Beta Stromgren star system, following the path of the Vega Nine probe which has traveled twenty-three parsecs beyond the farthest manned Federation exploration. In the staff meeting, Data conveys that the probe has discovered that the star in that system is in the final stages of an alternating cycle of expansion and collapse, which will soon result in the star going supernova. Tam interrupts Data out of frustration in Data's focus on tertiary background information and leaps ahead, explaining that the real focus of the mission is centered on the discovery by the probe of what appears to be a "living" starship possessing an unknown energy source, in orbit around the star. This object has been code-named "Tin Man" by Starfleet.
Troi is confused as to why Starfleet has made the mission so urgent, and Picard informs her that the issue is the Romulans, at which Tam expresses frustration with himself at forgetting to address this in giving the overview of the mission. After failed attempts at long-range subspace linguacode messages, Starfleet has ordered that the Enterprise to set course for Beta Stromgren as quickly as possible, as that sector of space is claimed by the Romulan Star Empire. As the Romulans routinely monitor the telemetry of all Federation deep-space probes, Starbase 123 has detected that the Romulans have dispatched two Template:ShipClass Warbirds in an attempt to reach "Tin Man" before the Federation. While these class Warbirds are slower than the Template:ShipClass starships, it is essentially a race to get to "Tin Man" ahead of the Romulans. As Data holds an honors degree from Starfleet in exobiology and is considered by the command staff as the on-board expert in the field, Picard then orders Data to head-up the life sciences team for the mission.
After the meeting is adjourned, Picard and Riker talk further with Tam, with Picard expressing his concern about Tam's initial omission during the briefing about the Romulans, since the possibility of an encounter with them during the mission was vital information that Tam did not properly prioritize within the parameters of the mission. Tam apologizes for not mentioning it earlier in the briefing, stating that he was distracted. Riker is perturbed by this seeming pattern of carelessness in Tam's professionalism, and Tam picks up his thoughts and angrily counters Riker by stating that "And no Billy-boy, I wasn't distracted on Ghorusda. If Captain Darson had listened to me no one would have died!" Apparently this does little to change Riker's opinion of Tam's history, and in fact in the next breath Tam confirms that Riker doesn't believe what he's saying.
Still two days out from the Beta Stromgren system, Picard confers with Doctor Beverly Crusher and Deanna Troi because of his concerns about the stability of Tam, who Starfleet considers crucial to the mission and upon whom Picard is forced to rely. Picard is surprised when informed by Crusher how high on the ESP scale Tam is, and how he is considered to be a prodigy when it comes to telepathic abilities. Troi explains that this is due to Tam being born telepathic, which is very uncommon in Betazoids, who usually develop their telepathic abilities in adolescence. Such Betazoids rarely if ever lead normal lives as the "noise" of hearing other people's thoughts during early development is often overwhelming, even incomprehensible. Early diagnosis and training helped Tam to adjust, though this has led to occasional need for hospitalization and therapy to deal with the stress, hence her contact with him at the university while studying psychology. As a result of his background, this has prompted Tam to seek assignments where he is more isolated from other humanoids and pursuing the more unusual lifeform assignments.
As the Enterprise races towards its destination, acting Ensign Wesley Crusher notices that the navigational sensors are picking up an anomalous "echo" which matches their speed and course. Lieutenant Worf confirms that something does appear to be shadowing their flight path, yet doesn't fully register on their sensors.
Data, who has the bridge, surmises that since there is no known naturally-occurring phenomenon that travels faster than warp one, it must either be a sensor malfunction, or another vessel is following them covertly. Worf declares that it is not a sensor malfunction, yet Crusher is confused with the easiest explanation that a cloaked Romulan vessel is following them, since if it were a cloaked warbird, they should not be picking it up at all. La Forge speculates that if they are pulling an extreme amount of power for some other system, they may not be able to fully cloak, thus being picked up faintly on the navigation sensors. Worf is ordered by Data to continue monitoring the "echo" and if it changes course or behavior, to go immediately to yellow alert.
Deanna Troi goes to Tam's quarters to check on him since he has not been out of his stateroom for quite some time. Tam at first is sarcastic and curt with Troi, but finally lets down his emotional defenses and confides in Deanna that the reason for his sequestering himself in his stateroom is because the number of people on the ship scares him. His inability to block out their thoughts and feelings threaten to overwhelm him, and that he never really could shut it all out.
Compounding Tam's own doubts about his reliability, are Riker and Picard's, stemming from the Ghorusda incident which Tam is well aware of. Troi presses him on what happened to him during the incident. Tam admits that he may have gotten "too close" to the Ghorusdians, which was not a unique thing to happen for him, and that it may have affected the professional detachment that is often needed in such missions. He confesses that he probably could have warned Darson more forcefully, and maybe avoided the disaster that resulted.
Troi puts forward the suggestion that he "ran away" because of the Ghorusda incident, by seeking out isolated assignments, such as being the only Federation delegate to be posted to Chandra V, giving him some measure of respite, and where Tam was up until his seeking out the assignment for making contact with "Tin Man". The Chandrans are a very peaceful and tranquil people, unlike humans, and this had been a relief for Tam, and one reason why Tam tells Troi that he likes being around Data since he is not bombarded by Data's thoughts. This perplexes Troi, since if the Chandrans proved some measure of relief for Tam, why would he volunteer to put himself into such an uncomfortable situation where he would be on board a vessel with over a thousand minds which would be quite uncomfortable for Tam?
Tam expresses that he couldn't help but volunteer, since he found "Tin Man" so compelling, so alien. That such a creature, intelligent, born in space, "swimming" in it as freely a fish does in water, so mysterious, ancient, alone and lonely. The depth and certitude of what Tam says about "Tin Man", even what emotions it is feeling prompts Troi to confront Tam about whether he is in contact with "Tin Man" telepathically since he seems to know things that no deep-space sensor telemetry could possibly convey. Reflexively Tam denies this, but then acknowledges that he does have a connection with the creature, but not on a conscious level. This news is shocking to Troi, since such a connection light years away is impossible, even for a telepath as gifted as Tam is, to which Tam replies "but maybe not impossible for 'Tin Man'."
The Enterprise finally arrives at the outer edge of the Beta Stromgren system and are at an ETA of 18 minutes until reaching "Tin Man's" location, but the astrophysics section reports that the star's collapse has accelerated and that the star could go supernova in minutes. They are also now getting a live data-relay from the Vega probe, facilitating close-proximity visual surveillance of "Tin Man".
As Tam and Deanna arrive on the bridge, Worf informs Picard that sensors are now detecting a subspace wave front of highly ionized particles ahead of the "echo" that has been following them for some time. Picard immediately takes the ship to yellow-alert as a Romulan Warbird becomes visible as it enters the system.
As the Romulan warbird approaches, it is detected arming its disruptors. Picard orders a red alert and to bring the shields to maximum. Riker orders the photon torpedo tubes be loaded, and Worf, as tactical officer to stand-by. Riker then wants an explanation as to how a Warbird which is supposed to be slower than the Enterprise could have arrived at almost the same time as they did. Picard interrupts the query, and orders that the Romulans be hailed, but Tam assures Picard that the Romulans are not interested in talking to Picard. At that moment, the Romulans fire on the Enterprise, while passing by her towards Tin Man. The attack caused her to take some casualties and disabling 78% of the shields. Tam pointedly states that the Romulan attack was incidental, and was employed simply to delay the Enterprise so they could reach "Tin Man" first. This assessment is supported by Data's analysis of readings taken of the Romulan vessel as it passed which showed that they had exceeded their ships warp output capacity by 30% in the effort to beat the Enterprise to "Tin Man". Riker notes that in doing so, the ship sacrificed its ability to return to Romulan space. Tam confirms Data's hypothesis by stating that the second Romulan ship is two days behind the one which just attacked the Enterprise and that their mission is indeed to reach "Tin Man" first at any cost. Picard is amazed that Tam could know this; Tam explains that he got it from the mind of the Romulan commander as the vessel passed the Enterprise.
Picard orders the ship to all stop, while La Forge effects repairs to the shields. He attempts to do this by reconfiguring the structural integrity field power supply and re-routing it to feed the deflector grid, having overridden the computer safety protocols by voice command authorization in order to do so as this would compromise standard safety limits. He further notifies Ensign Russell that he will have to watch the grid's lateral balance manually. He then calls Picard to tell him he should have partial shields restored within 30 minutes. to which Picard informs an exasperated La Forge he has 10 minutes to do so.
While the Enterprise awaits repairs, Picard begrudgingly cedes the "honor" of first contact to the Romulans, which greatly upsets Tam who worries that the Romulans may be able to win over "Tin Man". Picard assures him that the likelihood of that occurring is remote, and orders that life sciences and engineering continue to monitor "Tin Man" and to query the Vega Nine probe via long-range sensors.
As the crew waits for repairs to be completed, Data continues to monitor "Tin Man" from a workstation he has set up in his own quarters, and is accompanied by Tam who questions Data about this. Data informs him that he often works from his quarters as he has configured the workstation to display information more efficiently and quickly than workstations configured for other crew members. Tam explores Data's quarters, noting that it is rather "Spartan" and doesn't afford much room "to live", but then speculates aloud that he guesses Data doesn't sleep. Data confirms this by stating the while he has tried it from time to time but that he does not require it. Tam also appears intrigued that Data has taken up painting as a hobby.
Data, redirecting the conversation back to the task of monitoring "Tin Man", confirms that "Tin Man" has an internal layout similar to a space vessel, with interior corridors and chambers, and that it is maintaining an internal environment suitable for carbon-based lifeforms, even though there is no evidence of a crew aboard. Data then speculates that the lifeform was bred, or has adapted itself to serve a purpose and finds that "interesting".
This prompts Tam to pose a philosophical question to Data, as to why that is interesting, why must living beings have a purpose, or do they exist for no reason but to exist? Data states that he does not think he is qualified to answer such a question. Tam disagrees since he sees Data as uniquely qualified since he studies Humanity a great deal, and is a meticulous and honest researcher. This leads Data to question Tam's earlier statement that he could not read Data's mind. Tam assures him that he cannot, but that he does feel he understands Data pretty well. Tam then asks Data if it bothers him that he could not read Data's mind. Data replies that perhaps there is nothing there to read other than mechanisms and algorithmic responses. Tam acknowledges that possibility, then counters with the idea that it is perhaps just that Data is different, and that there is no sin in being different.
Data and Tam return to the bridge as the Enterprise is back under way, where Data informs the captain that they are picking up the Romulan equivalent of linguacode transmissions being directed towards "Tin Man". Tam scoffs at the idea that the Romulans would have anything in common with Tin Man. Riker counters by asking Tam why he thinks Tin Man would want to talk to him.
Just then, Data picks up sensor readings indicating that the Romulans are powering up their disruptors. Picard orders the ship back onto yellow alert and to prepare for evasive action should the Romulans change course as the ship is still vulnerable with only partial shields. Tam frantically interjects that they, the Enterprise, are not the target, but that "Tin Man" is. He informs Picard that the Romulans have orders to destroy "Tin Man" if they can't secure the alien. Picard orders the speed increased and to hail the Romulans. Tam yells that the Romulans will not listen to him and concentrates mentally on the message:
- "Danger. Gomtuu. Do not allow."
This causes a dramatic response from the alien object. It begins a clockwise rotation, suddenly discharging a massive energy wave which spreads throughout the star system, destroying the Romulan Warbird and striking the Enterprise causing a partial failure in the ship's main computer. This sudden and deadly turn of events makes obvious to Picard that Tam Elbrun has indeed made contact with, and awakened his "Tin Man".
The crew begins to effect repairs, with La Forge having to take the warp drive off-line in order to re-calibrate its regulators, and begin to bring the main computers back online. Riker has him make the first priority getting the shields to function, since there was still a threat of Romulan attack.
As Tam is checked out in sickbay after what appeared to be a seizure on the bridge following his frantic contact with "Tin Man", Picard presses him to be more forthcoming and explain exactly, and to what level of contact Tam has had with "Tin Man". Tam explains that he only sent out a mental warning, but that he had been in contact on an emotional level with "Tin Man", which calls itself Gomtuu. He then relays that Gomtuu is of an ancient species, most likely from beyond the galaxy, and that there were once millions of them, but now it is alone and perhaps the last of its species.
Picard suggest that Tam attempt to ask Gomtuu to return to Federation space, or at least move away from the Beta Stromgren star. Tam explains that Gomtuu knows the star is about to go supernova, and that is why it is in the system, in order to commit suicide. Long ago, there was some sort of explosion in space near Gomtuu, which emitted high levels of radiation which penetrated its outer layers, and killed the crew which inhabited Gomtuu.
As Tam relates what he senses of Gomtuu's history, he begins to be overwhelmed by the sense of loss and anguish which Gomtuu feels. Troi cautions Tam again about losing himself in his emotional connection to Gomtuu. Tam states that he can't do anything more to avert Gomtuu's suicide without physical contact with Gomtuu, and that he needs to be aboard it. Picard states that he would not risk such an action given Tam's inability to keep perspective, as evidenced by Tam's lack of regard to the Enterprise or her crew when he rashly warned Gomtuu about the Romulans. Tam notes to Picard that while he is right in having misgivings about him, that the only way for them to not fail in their mission is for Picard to trust him.
La Forge attempts swapping out the main sensory array control circuits with the secondary system ones to gain a minimum beam scan with the ships sensors. This works, and restores partial long-range sensors, where they pick up the second Romulan Warbird approaching the system. This underscores the needs to regain shield function, even though it will not protect the ship should the star go nova.
Picard asks Troi and Data their views about Tam, as Data has developed an affinity with him and Troi from her background with him. Troi again expresses the precariousness of Tam's emotional stability though both Data and Troi agree that Tam's motives are genuine and not in question. Data suggests that Data could act as an oversight guide for Tam if he were to accompany him in beaming over to Gomtuu.
The Romulan Warbird finally arrives in system and decloaks next to the Enterprise. The Enterprise hails the Warbird in an attempt to parlay, and the Warbird declares it has the right to retaliate against Gomtuu for the destruction of the first Warbird.
Tam and Data are allowed to beam over to Gomtuu. Direct and full contact between Tam and Gomtuu is established almost as soon as they arrive and Tam is overcome with a flood of thoughts from Gomtuu. Data sees Tam's distress and begins to call for an emergency beam-out, but Tam has him call it off explaining that Gomtuu was trying to relay an entire lifetime's worth of information in a few seconds, but has slowed down to where Tam could cope with it.
Gomtuu brings up a power shield of unknown type, which breaks the Enterprise's transporter lock, and reflects back any attempts at sensor scans. The warbird begins to move towards Gomtuu, with the Enterprise following her in. Tam and Data begin to explore the interior of Gomtuu, which exhibits the ability to change its interior structures, and extrude itself into various shapes and forms. Data reads a larger chamber twenty meters ahead of the corridor they are walking through, and Tam states he knows now all about Gomtuu, including the existence of the chamber ahead. They arrive at an area in the corridor which opens up and reveals the chamber, which Tam explains was once the control area of the vessel from where the crew guided their journeys. Tam explains that the ship and crew existed in a symbiotic relationship, and that once the crew was killed, Gomtuu no longer had a reason to exist. Data says, "Is that the purpose of existence? To care for someone?" Tam says it is for him – and that Troi was correct, that he could easily "lose himself" here. Data reminds him that their objective was to bring Gomtuu out of danger and report their findings to Starfleet, to which Tam confesses that he has no intention of returning to the Enterprise.
During this time, the Romulan commander threatens to open fire on the Enterprise if they interfere, which is a second warning from their first communique. Picard informs him that they intend to do everything in their power to defend the space creature, and cuts off communications as the Enterprise prepares for battle with its now partially functioning shields. Just as this happens, sensor readings indicate that the star has begun an irreversible reduction in diameter and is beginning its final collapse into a supernova.
On board Gomtuu, Tam implores Data to explain to the Enterprise crew why he has chosen not to return, that he will carry out the main mission objective in saving Gomtuu from destruction by bonding with the creature; in doing so, Gomtuu in essence will also save Tam. Tam has taken the place of the long-lost crew for "Tin Man"; it now has a reason to live again. Meanwhile, Tam is no longer inundated by the thoughts of others. Now hearing only Gomtuu, Tam at long last has found the mental peace-of-mind long denied him due to his hypersensitive telepathic abilities; he says to Data, "This (Gomtuu) is where I belong."
Gomtuu once again emits a powerful energy wave, this time throwing both the Enterprise and the Romulan warbird (more gently this time) out of the Beta Stromgren system. By the time the Enterprise comes to a full stop, it is close to 3.8 billion kilometers from where they previously were. Moments later, the star Beta Stromgren finally collapses into supernova.
As the star explodes, the crew is gravely concerned that Data, Tam and Gomtuu are lost, but at that moment Data reappears on the bridge (courtesy of Gomtuu) and says it will be "difficult to explain" what happened. The Enterprise sets course for Starbase 152 in order to effect full repairs and undergo a systems inspection with Gomtuu's whereabouts now unknown.
Data, alone in the observation lounge, is joined by Troi at his request. Data states that it was Tam's expressed wishes that Data explain his decision to remain with "Tin Man" and that he hoped that Troi would understand. Data explains that he was witness to something "remarkable". Both Tam and Gomtuu were individually wounded and isolated, but with their joining, they had both been healed. Their grief transmuted into joy, loneliness into belonging. Troi expresses surprise that Data truly does understand. Data affirms that he does, and that when he was transported by Gomtuu back onto Enterprise, Data realized that that is where he himself belonged.

Story and script
- Writers Dennis Russell Bailey, David Bischoff, and Lisa Putman White based this episode on a short story titled "Tin Woodman" that Bailey and Bischoff wrote in 1976. It was first published in the December 1976 issue of Amazing Stories, and served as the basis of a novel of the same name published by Doubleday in 1979. The original story was nominated for a Nebula Award in 1977. (Star Trek: The Next Generation Companion 2nd ed., p. 123)
- According to Bailey, the trio were inspired to write a script for the series after watching "Samaritan Snare", which he considered "the most abysmal piece of Star Trek ever filmed." (Captains' Logs: The Unauthorized Complete Trek Voyages, p. 180)
- Bailey noted that only two of the three were given credit on the script because the rules at the time would not allow three people to be paid as a writing team. As such, he used Lisa Putnam White's middle name as his middle name. 
- A line from the script suggested that Captains Picard and DeSoto had previously served together as lieutenants. 
- First UK airdate: 18th March 1992
- The ambient sounds that Gomtuu made were derived from sounds recorded from sound effects editor Jim Wolvington's stomach through a stethoscope while he was eating pizza. (Star Trek: The Next Generation Companion 2nd ed., p. 123)
- The growing chair was created by reversing a time-lapse film of a wax chair melting. (Star Trek: The Next Generation Companion 2nd ed., p. 123)
- This episode was the first to have its music composed by Jay Chattaway who was called in as a guest composer. Wendy Neuss and Peter Lauritson had a three hour spotting session with Chattaway and recalled his whale sounds from his work on the action film Red Scorpion. Chattaway recalls, "As a result of composing music for Jacques Costeau over the last five years, I have an amazing library of sounds, which we digitally sampled and used in "Tin Man". We also used an Electronic Valve Instrument (EVI) to create those ancient flute sounds. I think we used two players for the electronics. Peter Levin was our whale specialist on "Tin Man". I use synthesizers to do certain things that an orchestra can't. The organic sound for the Tin Man was done by two synths, both playing Australian 'didjeri-doo' loops." (The Official Star Trek: The Next Generation Magazine Vol. 18, p. 34)
- Gomtuu's attack special effects is a reuse of V'Ger's "evolution" in the ending part of Star Trek: The Motion Picture. It has been edited to fit the scene in this episode.
- This episode is the first one to mention the name of the Template:ShipClass Romulan Warbird.
- Director Robert Scheerer commented, "I was disappointed with 'Tin Man.' It was an interesting show, but I don't think that I pulled off the sense sufficiently of the living ship. God knows I tried. We struggled and struggled with it, but we ended up a little bit insufficiently fulfilled – I thought. An interesting show, but I don't think I did my best work in that show." (Captains' Logs: The Unauthorized Complete Trek Voyages, p. 5)
- A mission report for this episode by Patrick Daniel O'Neill was published in The Official Star Trek: The Next Generation Magazine Vol. 13, pp. 63-66.
- This episode was nominated for an Emmy Award for Outstanding Achievement in Special Visual Effects.
