A freak accident during an experimental space mission catapults Astronaut John Crichton across a thousand galaxies to an alien battlefield.
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.
