Astronaut John Crichton attempts to use the Earth's atmosphere to propel his module at high speeds. He is hit by a radiation wave and is sucked through a wormhole into a distant part of the universe--straight into the middle of a space battle.

A peacekeeper ship is approaching Moya, so Crichton and Aeryn pose as peacekeeper officers on a secret mission while everyone else gets locked into cells to make the deception seem realistic. The peacekeepers that come aboard have some secret cargo. But when their secret cargo escapes, no one on board is safe.

Moya is hiding from a peacekeeper command carrier in an asteroid field. The crew receive a distress call and Crichton, Zhaan and D'Argo go down to one of the asteroids to rescue a women who has an unusual appetite.

Rygel steals a transport pod and goes to the peacekeeper command carrier to betray the others. However he ends up returning to Moya with Crais who wants asylum. Crichton decides to destroy Scorpius' Gamac Base to give Moya time to escape.

While waiting inside a transport pod to be picked up by Moya, Zhaan tells Crichton about being accused and tried for murder during his absence.

Talyn lands on a planet covered mostly with vegetation that will help him to heal. Crichton, Aeryn and Crais leave the ship in search of Xhalax.

A group of escaped prisoners come aboard Moya followed shortly by Aeryn, Stark, Crais and Rygel who have finally returned from Talyn.

Crais gets Talyn to starburst inside the command carrier, causing it to collapse in on itself.

60 days on and Rygel is retrieving pieces of John and Aeryn from the sea bed. The diagnosan (Season of Death) re-crystalises them and they start getting to know the species that live on that world. Meanwhile, Scorpius and Sikozu are aboard a Peacekeeper Command Carrier on a recon mission. They attack a Scarren ship which provokes the Scarrens into declaring war on The Peacekeepers.

With Sikozu's help, everyone manages to escape from the Scarren prison. Joining up with D'Argo, Jothee, Chiana and other Luxans they cripple and leave the Scarren ship and return to Moya. Crichton returns to the wormhole where he gets Einstein to give him the ability to build a wormhole weapon.
