UPN airs the 133rd episode of Star Trek: Voyager. 
Stardate not given: The Delta Flyer returns from a two-week mapping mission with a very cranky crew consisting of Chakotay, Neelix, Tom and Harry Kim. But upon their return, the Delta Flyer crew begin to suffer from hallucinations of a bloody battle – a battle in which there is no evidence of their participation. But Janeway’s concern grows as all four crewmen eventually recount their hallucinatory memories, which corroborate each other and create a consistent picture of the battle they fought – a battle in which they killed almost a hundred civilians. And the captain’s concern becomes horror as she, too, begins to remember having played a part in the carnage.
