A crew on a mission to deploy a Doomsday Device against an alien planet is captured and psychologically tortured.
- Binary Suns: The Ebonites' solar system is said to have two suns.
- Dark and Troubled Past: It turns out that every member of the crew has one. Part of the experiment consists of the supposed Ebonites playing upon their pasts while interrogating them.
- Downer Ending: Even worse than the 1963 original. In this case, it's one of the revival series' many Cruel Twist Endings.
- Earth All Along: The crew finds out that they were on Earth the whole time and that their interrogation was a psychological experiment.
- Gaslighting: The military uses elaborate special effects to imitate the Ebonites' capabilities.
- Gone Horribly Right: The interrogation experiment showed the crew's psychological endurance alright; unfortunately, it resulted in Naguchi being stabbed in the stomach while O'Keefe sets the device to blow and take the earth with it.
- Irony: As the narration points out, the General's experiment ends up destroying the very world he was seeking to protect.
- Laser-Guided Karma: The General ends up receiving severe repercussions for his interrogation experiment. This was probably to counter the Karma Houdini ending of the original.
- The Mole: One of the experiment's tactics was making the crew think there was a traitor in the ranks'. Unfortunately, when they made it look like it was Naguchi, it resulted in Valentine stabbing him in the stomach.
- My God, What Have I Done?: After realizing that she set the device to blow on Earth, O'Keefe spends her final moments in grief over it.
- Nothing Is Scarier: What exactly the Ebonites look like is not shown.
- Not Quite Dead: At first, it looked like Chaumsky had been killed during her interrogation, but turned out to be a simulated corpse.
- Only Sane Man: After Chaumsky found out about the experiment, she begged the General to stop, but she was ignored. Turns out they should've listened to her.
- Taking You with Me: At the end of the experiment, The Stoic O'Keefe has reached her breaking point even more than the others and ends up setting the Earth-Shattering Kaboom device to blow, believing that she and the others were going to die in enemy territory, unaware they were really on Earth.
