A shuttlecraft flies in space as we hear Geordi give a personal log entry. He's traveling to Risa to attend a cybernetics symposium and for shore leave. Although enjoying a drink, Geordi has become bored, so he asks the computer for a guessing game. While playing, he notices a Romulan warbird has decloaked ahead, so Geordi stops the game and tries to send a distress signal, but nothing works, as the shuttlecraft is locked in a tractor beam and he's immediately transported off.
Meanwhile, the Enterprise
is en route to the Klingon colony of Krios, which is in the midst of an insurrection. The Klingon governor, Vagh, has accused the Federation of arming the rebels, and Klingon ambassador Kell is accompanying them to examine the evidence, personally requesting Picard's help.
Aboard the warbird, Geordi is dragged into a room and strapped into a chair, where Romulan Subcommander Taibak "warmly" greets Geordi. After an impersonator is sent to Risa in Geordi's place, Taibak has Geordi's VISOR removed, and connects a device directly to Geordi's neural implants. This device sends various images, primarily horrifying, directly to Geordi's visual cortex, making him unable to ignore them. A shadowy figure with a familiar voice
asks if there'll be any trace of their conditioning. Taibak assures her that because of Geordi's preexisting implants, any conditioning would be impossible to detect. He changes to another disturbing image, as we zoom in to see Geordi screaming in agony.
We return to the Enterprise
, where Ambassador Kell speaks with Worf. Kell tells Worf that he did the Klingon Empire a favor in killing Duras, though Worf retorts that he had his own reasons
for doing so.
We cut to Ten Forward, or rather, a holographic recreation where Geordi, Taibak and his Romulan subordinates are sitting. Taibak orders Geordi to shoot and kill the holographic Chief O'Brien with a phaser, but while walking over, Geordi hesitates. After a little coercion, Geordi shoots and kills "O'Brien". Taibak tells his officers that Geordi needs another conditioning session.
On Krios, Picard vehemently denies the Federation's involvement until Vagh presents a confiscated phaser rifle taken from a rebel stronghold. It seems to be Federation-made. Picard asks if he may take it to analyze, to which Vagh is welcome. He's confiscated plenty.
Geordi returns to the Enterprise
with no memory of his abduction and brainwashing. Data starts to find sporadic E-band emissions, and also works with Geordi in determining the legitimacy of the phaser rifle. Through careful examination, Geordi and Data find that the rifle had been charged with a power source in the terahertz range. Data notes that at least 327 species use this range, but Geordi narrows it down by who would benefit by driving a wedge between the Federation and the Klingons.
Geordi and Data join Picard in another meeting with Governor Vagh, concluding that the weapon is a Romulan decoy: a physically perfect duplicate, but being charged with Romulan energy sources, traces were left behind. Vagh is skeptical, since Krios holds no strategic value to the Romulans, so he still wants his own people to verify the findings. While in the office, La Forge's VISOR receives another distinctive E-band transmission.
In Ten Forward, we see Geordi in a setup similar to the Romulan holorecreation. However, this time, Geordi simply spills his drink on O'Brien.
On the bridge, Data and Riker detect another E-band emission, much larger than the previous ones. Acting under mind control again, Geordi beams down a crate of weapons from a cargo bay to the surface, deleting the transporter logs afterwards. Just as the Enterprise
is about to leave, Vagh sends a transmission, telling Picard that they have intercepted the crate, and that they are not to not leave orbit until further notice, as a Vor'cha cruiser and 2 Birds-of-Prey decloak and intercept them.
Data finds that the memory chips in the computer were erased to hide the offender's identity and the power was routed through the replicator pathways to attempt to conceal its origin. Ambassador Kell offers to speak to Vagh, urging him to come to the Enterprise
to witness the investigation. Before leaving, however, Geordi meets with him in his quarters, where it's revealed that Kell has been conspiring with the Romulans
, being the one transmitting the E-band emissions. Kell tells Geordi that when Vagh arrives, Geordi is to assassinate him, claiming he is acting on behalf of the Federation in support of the rebels.
That night, Geordi has difficulty sleeping, first contacting Chief O'Brien to see if he's okay, then going to sickbay to have his VISOR checked by Dr. Crusher.
The next morning, Vagh arrives to witness the investigation, only at Kell's insistence. Kell suggests visiting Cargo Bay 4. Picard agrees. Following a mounting trail of evidence, Data finds that the E-band transmissions would be compatible with La Forge
's VISOR. He then goes to the shuttlebay and determines that the memory chips in La Forge's shuttlecraft have been replicated by Romulans, and that the hull has been subjected to stresses consistent with a tractor beam. He then calls Worf, ordering him to take Geordi into custody immediately.
Meanwhile, Geordi has arrived in Cargo Bay 4, armed with a small phaser as per Kell's instructions. Seeing Geordi, Worf immediately rushes down, but gets restrained by Vagh's guards, erroneously mistaking Worf's actions as hostile. Worf yells out a warning to Picard, who stops Geordi. Vagh is quite convinced of a Federation plot against him, leaving Picard at a loss until Data arrives, revealing that La Forge has been acting under Romulan control, explaining the E-band transmissions that have preceded each suspicious act aboard the Enterprise, which were transmitted directly to La Forge's brain through his VISOR. Kell, anxious to divert suspicion away from himself, asks whether a cloaked Romulan ship could be the source of the signals. Data says no, the signals would have to have been transmitted in close proximity to La Forge by a Romulan agent. As to who that agent is, Data reveals that only two people were close to La Forge at all three times when a signal was recorded: Picard and Kell.
Data suggests that the Romulan agent must be hiding an E-band transmitter on his person. He recommends both Picard and Kell consent to a search. Kell blusters that, as a representative of the High Council, he will not consent to be body-searched, but Vagh has his bodyguards place the ambassador under arrest, saying they will take him back to the planet and search him there. Kell formally requests asylum aboard the Enterprise. Picard coolly rejoins that he will be happy to grant asylum – after Kell is absolved of any crime. Vagh signals the planet, and the Klingons are beamed away.
Later, Geordi is talking to Troi, where he begins to realize that his memories of his trip to Risa are false. Troi promises to work with him to restore his memory, and she begins by asking La Forge what happened after he saw the Romulan ship – a question that leaves La Forge stumped, and worried as the full horror of the violation against him begins to sink in.
Tropes featured in "The Mind's Eye":
- Armor-Piercing Question: Technically an Armor-Piercing Answer: Geordi's response to Troi's question about the Romulan ship comes out almost automatically, as if he didn't even have to think about it. And it's at complete odds with his implanted memories, and is the first step toward unraveling what was done to him.
Geordi: No, the first thing I did was...wait a minute...
- Asshole Victim: Kell tells Worf that he did a service in killing Duras, saying that some High Council members were apprehensive about him getting named Chancellor.
- Chekhov's Gun: The E-band blips turn out to be Kell's method of giving Geordi instructions.
- Cold-Blooded Torture
- Dissonant Serenity: Geordi smiles and enjoys a drink after shooting the holographic Chief O'Brien.
- Dirty Coward: When Kell is exposed, he plays the asylum card to avoid the wrath of his fellow Klingons. Picard tells him to screw himself.
- Early-Bird Cameo: This is the first appearance of Sela, Tasha Yar's half-Romulan daughter, but since she is only seen very briefly and with her face obscured by shadows, the proper reveal of her identity won't happen until two episodes later.
- Fake Memories: Taibak makes Geordi think he really did go to Risa.
- Faux Affably Evil: Taibak while beginning the brainwashing process.
- Karma Houdini: Subcommander Taibak gets away with torturing and brainwashing Geordi and almost sparking a war between the Federation and the Klingons.
- The Ludovico Technique: Geordi is brainwashed by being shown horrifying images sent directly to his visual cortex via his VISOR's neural implants. Literal Eye Scream ensues.
- Manchurian Agent
- The Mole / The Quisling: Ambassador Kell.
- Pardon My Klingon: Picard vs. Vagh swearing contest. Picard wins.
Vagh: You speak the lies of a taHqeq!
Picard: Vagh ghay’cha’ baQa’!
Vagh: You swear well, Picard. You must have Klingon blood in your veins.
- Realpolitik: When Kell tells Worf that a lot of people in the Klingon government tacitly approve of his killing Duras, Worf protests that his motives were personal. Kell scoffs, "Motives. Who cares for motives? Humans perhaps. What matters is you acted that day."
- Recycled In Space: The Manchurian Candidate IN SPACE!
- Shoot Your Mate: Geordi has to shoot a holographic Chief O'Brien in his programming as an assassin. His brief hesitation leads to more brainwashing.
