Members of the Voyager crew clandestinely participate in a hidden holodeck program where the ship's Maquis members stage an insurrection. Word gets out and Tuvok confesses to writing the program as a training guide for security officers but never finished it because the merged crew seemed to be working well together. When Tuvok and Paris get trapped in the program, they realize that former crew mate and Cardassian spy Seska had added her own twist to the story.
