(written from a Production point of view)
Something is luring a former away team back to the planet they once investigated five years ago - an away team that La Forge was a part of.
In the observation lounge, Jean-Luc Picard, William Riker, Geordi La Forge, and Susanna Leijten are viewing a sensor log from an investigation Leijten and La Forge were part of five years ago, while attached to the USS Victory. They were investigating the disappearance of 49 colonists from the Tarchannen III outpost. The other members of the Victory away team, Brevelle, Mendez, and Hickman, have now deserted their posts without any warning. A Federation supply ship has spotted Hickman's stolen shuttle and it is heading back to Tarchannen III. Leijten and La Forge are the only two remaining members of the Victory away team not to have disappeared.
Act One Edit
- "Captain's log, stardate 44664.5. We've set a course to intercept Lieutenant Hickman's stolen shuttlecraft, and hopefully to discover the whereabouts of the other missing officers."
La Forge and Leijten go to Ten Forward to reminisce about their days on the Victory and catch up with events, such as Leijten discussing on how she almost married Paul Bogrow, a man she could barely stand. Helmsman Graham reports that they have entered the Tarchannen system, where the crew finds the shuttle. Worf hails the shuttle but Hickman doesn't respond. The shuttle approaches the planet too fast and burns up in the atmosphere. Sensors detect two more shuttlecraft on the surface, but no life signs. Picard orders an away team to investigate.
On the surface, the away team discovers the shuttle Cousteau, which Mendez stole from the USS Aries. While La Forge checks out the shuttle, Leijten finds strange footprints in the sand, and she moves toward them for a closer look. Worf tells Riker he has a feeling they are being watched. La Forge returns with chilling evidence: a torn Starfleet uniform.
La Forge notices that Leijten is missing. The other members of the team spread out to look for her. When La Forge follows some footsteps in the sand, he finds her staring blankly into the darkness. She claims she can feel the missing crew's presence. She starts to shake violently, screaming, as La Forge calls up a medical emergency beam-out.
Act Two Edit
Leijten wakes up in a bed in sickbay. Dr. Beverly Crusher reports that her blood chemistry is off and that she's had a histamine response to something she can't identify. Leijten feels compelled to return to the surface but Crusher orders her to stay on the Enterprise until she can find out what is wrong. Leijten protests, but Picard confirms the order.
Leijten and La Forge are walking in the corridor when Leijten's hands start to tremble. She expresses the fear that whatever is happening to the away team members is happening to her.
On the bridge, Data examines evidence collected from the survey. He has found some alien cells that don't belong to any known Tarchanen lifeform. While Data attempts to find a match for the cells and footprints, La Forge and Leijten decide to go through the mission log to see if there is any commonality they missed that would make the crew return to Tarchanen III to be abducted.
As they examine the logs, Leijten becomes agitated and demands to go back to the surface. As she leaves, she begins to shake uncontrollably and collapses as he and Lt. Wallace rush over to help. La Forge notices a strange blue growth pattern on the back of her neck and that her fingers have grown together.
Act Three Edit
Leijten is in sickbay with the lights dark, as she has developed an extreme sensitivity to light. The strange growth patterns now cover most of her body. La Forge comes to visit and comfort her. Crusher discovers that Leijten's cells have now changed to match the alien cells found on the surface. Crusher theorizes that the missing crew were not abducted, but transformed into a different species. Crusher informs La Forge that he will most likely be next and that he should stay in sickbay. He insists that he needs to work on the investigation and leaves, recommending that the computer monitor him.
He returns to engineering and begins to thoroughly examine the logs again. He runs several scans on the data, but nothing comes up. Data arrives to ask about his progress and if he can help, but La Forge is exasperated and says he just needs to go over it again.
Meanwhile, Leijten's body makes more drastic changes. Alyssa Ogawa shows Crusher that her body can simulate light in a radiant reaction. Furthermore, her body temperature dropped drastically, despite the T-cell inhibitors. Crusher tries to scan her, but the readings are faint. She orders a full genetic analysis.
La Forge then notices a slight shadow on the visual log that he cannot identify. He tells the computer to create a holoprogram based on the sensor log data. As he goes to the holodeck he notices that his hand has begun to tremble as well.
Act Four Edit
In the holodeck, La Forge uses the computer to remove people and their shadows from the simulation until only the strange shadow is left. He then uses vector analysis to determine the location of the object causing the shadow. He is shocked to discover a human-sized invisible shape. He then slumps down in pain. The same physical changes that Leijten experienced are starting to happen in his body.
In sickbay, Crusher and Ogawa have found a parasite in Leijten's thymus which is transforming her body. Not like a normal parasite, it's using Leijten's immune system to propagate genetic changes to match its own. They have to act quickly, while there is still DNA intact, to help reverse the damage. Martinez comes to assist in the procedure.
Dr. Crusher operates on Leijten and removes the parasite in time. She begins to return to normal. She tries to find La Forge, but he has disappeared. The computer reveals the last location of La Forge and Picard sends Worf, Riker and a security detail to the holodeck. When they arrive they see what La Forge saw, and Worf discovers a grisly scene: La Forge's torn uniform and his VISOR. Riker steps back as he gazes at the eerie image, thinking that this is what the chief engineer has become. In the transporter room an invisible shape attacks Hedrick, the transporter operator, overrides the transporter lock out and beams to the surface. During the beam-out, the image of what La Forge has transformed into, appears for the moment before the transport is complete.
Act Five Edit
With less than an hour left before the transformation is complete, Data develops a method to detect the aliens using ultraviolet light from an emergency beacon, while Hedrick finds the transport location and Riker and Worf prepare their search method. Meanwhile, Leijten has come around, the changes in her hands and face reversed. She wants to find La Forge, and tells Crusher that the process was actually a method of reproduction, a metamorphosis; they multiply by infecting humanoids with the parasite. She also says she has to go with them to find him, as they won't be able to detect him without her.
Crusher, Leijten, Riker, Worf, and Data beam down to the surface. They find the nearly transformed La Forge, along with the fully transformed creatures that were once Brevelle and Mendez. The latter two flee, but Leijten was able to talk with La Forge, breaking into the conflict between his humanity and the metamorphosis trying to win control. Breaking through the fear, he reached out and grabbed Leijten's hand and the two embraced, allowing Crusher to beam both of them to sickbay.
On the Enterprise, Crusher is able to save La Forge, but sadly it's far too late to save Brevelle and Mendez. Based on his own experience, he reports that the creatures are unintelligent: operating entirely on instinct. He turns to Leijten and notes that he would not be able to recognize her voice in a matter of minutes. Picard decides that the inhabitants of Tarchannen III should be isolated. He orders warning beacons placed around the planet and on the surface to warn others of the aliens there. La Forge thanks Leijten for her assistance in helping to find him. He remarks that while he was transformed, he had no idea who Leijten was but somehow he both believed and trusted her. "Must have been because of all the good advice I used to give you", she says.

Background information Edit
Production history Edit
- Final draft script: 11 January 1991 
- Filmed: 16 January 1991 – 25 January 1991
- Premiere airdate: 25 March 1991
- First UK airdate: 19 October 1994
Story and script Edit
- The original spec script submitted by Timothy DeHaas involved two non-regular crew members undergoing the transformation. Michael Piller recalled, "It was a very tough script to solve...It was very heavy on point of view and stylistic devices we didn't want to do." (Captains' Logs: The Unauthorized Complete Trek Voyages, p. 218)
- According to Brannon Braga, early versions of the script had a romantic relationship between Geordi and Susanna, but it was felt that the engineer deserved "a break" from failed romances after "Booby Trap" and "Galaxy's Child". (Star Trek: The Next Generation Companion 2nd ed., p. 159)
- Braga's first draft was much more horrific, with many more aliens on the surface. In this version, La Forge was not transformed. However, to make the show work, Braga felt it was necessary to include La Forge in the change and reduce the terror to a "restrained and psychoanalytical" level. (Star Trek: The Next Generation Companion 2nd ed., p. 159)
- "Identity Crisis" was filmed between Wednesday 16 January 1991 and Friday 25 January 1991 on Paramount Stage 8, 9, and 16.
- For a single frame (at approximately 17:08 on a Region 1 DVD and 16:27 on Region 2 DVD), a graphic displaying the Star Trek: The Next Generation logo can be seen on a computer readout in engineering.
- Regarding the use of ultraviolet effects in the episode David Livingston recalled, "We were talking about how we're going to make these guys glow and Peter Lauritson says to me, 'Why don't we try ultraviolet?' I said because we had done a test the year before. I almost dismissed it, but then pulled out the tape and looked at it and said this stuff is great. [I] went to Michael Westmore and Bob Blackman and said we want to do this, and they designed these suits and we painted them with u/v and put these contact lenses into this woman's eyes that glowed. It was fabulous and we got Mark and Brian to walk around in these suits. LeVar looked fabulous.
- "We used heavy blue light for the set lighting, and it's different lighting than you see elsewhere, because all of the source coming from behind the camera is blue light. That's a decision we made and it should look harsh, and unrealistic and not well lit because it's not lit from one single blue source. It's basically a beacon shining out. It looked different than anything else and that was intentional. What I was surprised at was how powerful the u/v reflected back, and MTV is using it a lot now. I liked our use because it was integrated into the story. We used it to make it work dramatically rather than doing it as an effect. To me, that was a major accomplishment. We didn't do it to just be glitzy, we did it because it tied in dramatically with the story." (Captains' Logs: The Unauthorized Complete Trek Voyages, p. 218)
- It took four make-up artists six hours to apply the full Tarchannen III species make-up to LeVar Burton. According to Michael Westmore, it was the longest make-up ever done on The Next Generation. ("Departmental Briefing, Year Four: Make Up", TNG Season 4 DVD special feature)
- In the scenes set in the year 2362, crewmembers of the USS Victory are correctly seen wearing the old Season 1 and 2 Starfleet uniforms (La Forge wearing command red again) and using the early "dustbuster" type 2 phaser. La Forge additionally wears an older version of his VISOR.
- Although the past scenes are set in 2362, the stardate given starts with "40", which would imply 2363.
- The command of the USS Aries was previously offered to Riker upon the retirement of her captain, as seen in "The Icarus Factor".
- When Crusher is ready to operate on Leijten, Martinez is seen to place a neural stimulator over her head, like the one prominently used on Riker in "Shades of Gray".
- Other species that propagate by infusing other species with their DNA and transforming them include the Taresians, Kobali and Loque'eque.
Cast and characters Edit
- Marina Sirtis (Deanna Troi) does not appear in this episode.
- This episode features some rather unusual guest stars, with former Miss Universe Mona Grudt as Ensign Graham and LA disc jockeys Brian Phelps and Mark Thompson as two of the Tarchannen III aliens. Phelps and Thompson filmed their scenes on Wednesday 23 January 1991 on Paramount Stage 16 and interviewed cast members Jonathan Frakes, Gates McFadden, Marina Sirtis, and Michael Dorn for their radio talk show The Mark & Brian Show. The call sheet features the scheduled times for the interviews.
- Michael Piller remarked, "It was a very complicated, complex production that the director did a terrific job on. It had scenes within scenes and I was very happy with the show. It may not have been one of the best scripts we wrote, but it's a great example of how those guys in production can really turn out a helluva product." (Captains' Logs: The Unauthorized Complete Trek Voyages, p. 218)
- Winrich Kolbe recalled, "That was an interesting show and a lot of [work]. First of all, LeVar Burton is a hell of an actor and it's a lot of fun working with him, even though I'm sure there was a lot of pain and agony on his part going into that suit. Technically speaking we didn't make things any easier for him because we had to light everything with black light. So we're kind of restricted camerawise to do what we wanted to do because of all of those tremendous black light units. It was a hell of a set, but a technical nightmare. But everybody seems to be happy about it." (Captains' Logs: The Unauthorized Complete Trek Voyages, p. 218)
- A mission report for this episode by Patrick Daniel O'Neill was published in The Official Star Trek: The Next Generation Magazine issue 16, pp. 54-56.
- This episode was nominated for an Emmy Award for Outstanding Achievement in Makeup for a Series.
