Roj Blake, a political dissident who is arrested, tried and convicted on false charges and deported from Earth to a prison planet. He and two fellow prisoners commandeer an abandoned alien spacecraft, rescue two more prisoners and are joined by an alien guerrilla with telepathic abilities. In their attempts to stay ahead of their enemies and inspire others to rebel, the group encounters a wide variety of cultures on different planets throughout the galaxy, and are forced to confront various human and alien threats. The group conducts a campaign against the authoritarian Galactic Federation until an intergalactic war occurs. Blake disappears and Kerr Avon leads the group.. When their spacecraft is destroyed and one group member dies, they commandeer an inferior spacecraft and a base on a distant planet from which they continue their campaign against the Federation. In the final episode, Avon discovers Blake's location and suspecting Blake of betraying the group to the Federation, kills him. The group are then shot by Federation guards, who surround Avon in the final scene.
