Avon secretly takes over the ship and flies it through a field containing enzymes which eat away at the Liberator's hull. They reach the planetoid Terminal, where Avon believes Blake is residing.

Dorian, owner of the spaceship Scorpio, rescues the crew from Terminal. He tries to enlist the help of Orac to build a teleport mechanism for Scorpio and attempts to kill the crew.

The Scorpio, rendered inaccessible by an elaborate security system, is stolen by a native of the planet who seeks to escape. Avon completes the Scorpio teleport system with the help of Orac.

Dayna meets an old friend, Justin, to seek help with synthesizing an antidote to the Federation pacification drug. Servalan learns of Scorpio's visit to Justin's planet and of the genetic research he is performing there.

The crew rescue a protege of Ensor's who instead turns out to be his android creation seeking to unite with Orac.

After Orac traces Blake's trail to the planet Gauda Prime, Avon and crew travel there, leaving the destroyed Xenon base behind. Scorpio is attacked on approach to the planet and crash lands on the surface of Gauda Prime. Avon and crew travel in search of Blake, and discover that he may have sold out to the Federation.
