The Outer Limits 1963 S 1 E10 Nightmare

In response to an unprovoked nuclear attack from the planet Ebon, a group of soldiers–representing Unified Earth–is sent to fight the enemy on their alien world. Captured en route to Ebon, the soldiers undergo physical and psychological torture and interrogation at the hands of the Ebonites, who possess the ability to control physical abilities and senses. The prisoners become suspicious of each other when their captors claim they have received cooperation in obtaining military secrets, which is further complicated by each one's past and ethnic origins, along with the unexpected appearance of high-ranking Earth officers among the hostile aliens. The Earthmen are subjected to various interactive images of relatives and friends which have been implanted in their minds during questioning, allowing them to feel a false sense of security, or surfacing deeply hidden emotional conflicts. In the end, it is revealed that all of this is a military "game", organized by the Earth officers to test their troops' loyalty and valor under intense interrogation and psychological stress. The Earth-Ebon war itself is a fake, as the Ebonites' initial bombardment was unintentional and for which they had apologized. Unexpected accidents and deaths having occurred during the test, the Ebonites –who are, in actuality, a peaceful and honorable alien civilization– ultimately demand that such an immoral and inhuman experiment should end at once. Nevertheless they fail to prevent one last man from being killed, one of the conspiring Earth officers thought to be an illusion created by the Ebonites to trick the captives into revealing more information.
