Crichton must seek out an old friend who has gained too much knowledge about wormholes.

Jack (The Ancient) unlocks the wormhole knowledge in Crichton's mind so together they can build a device to destroy the Scarran dreadnought.

The women of Moya travel to a dead Leviathan to buy a sensor beacon for Moya which will allow her to appear to be a different ship. While there Aeryn and Sikozu spy on a secret meeting between the Peacekeepers and the Scarrans.

Moya arrives at Katratzi. Crichton attends the peace talks between the Scarrans and the Peacekeepers ...with a nuclear bomb.
