A group of convicts and outcasts fight a guerrilla war against the totalitarian Terran Federation from a highly advanced alien spaceship.
En route for the Federation planet Saurian Major, the Liberator encounters a small craft drifting in space, and the crew bring it aboard against Zen's advice. Later, Blake, Avon and Vila teleport down to attack the Federation communications complex on Saurian Major, leaving Jenna and Gan to watch the three cyrogenically-frozen passengers found aboard the vehicle. As Blake's team and a telepath named Cally try to infiltrate the base, the three aliens come out of hibernation.
