Tom Paris and Harry Kim are wrongly convicted of a terrorist bombing. Even though Janeway captures the true criminals, Tom and Harry are fitted with strange brain implants and imprisoned on a satellite. In the prison, the inmates have no supervision, no medical care, and all have implants which increase their aggressive tendencies. New prisoners and food-rations are delivered through a one-way chute. As days pass, the friends try to hold on to reality but find themselves turning on one another and taking drastic measures to survive and attempt escape.
