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.

Moya gets infested with bugs who have come on board to breed. They turn up the temperature to speed up the process but this causes Aeryn to get heat delirium as she is cold blooded. The bugs seem to be able to replicate members of the crew. And as if that isn't enough, a peacekeeper ship shows up.

The crew come across a ship that is molecularly de-stabilizing. D'Argo makes everyone bring it aboard when he discovers that there are Ilanics on board. Crichton goes on to the escape pod he gets a shock and starts experiencing strange visions of the future, firstly of himself and Matala, then of Moya's destruction.

A group of Tavleks come aboard for trade negotiations. Rygel takes a vitally important crystal from Moya to make himself seem wealthy. The Tavleks kidnap Rygel and take him down to the planet, leaving one of their wounded on board. Everyone goes to the surface to get him except Zhaan who stays on board to keep an eye on the Tavlek left behind.

The crew find an old abandoned peacekeeper ship adrift in space, on board they discover that Crais was there recently where he deposited a unit of techs to make repairs. Meanwhile Rygel learns that this was the ship where he was first held captive and starts getting paranoid. Things get even worse though when a group of fire breathing aliens show up.

The crew visits a planet full of happy workers. Soon D'Argo and Zhaan start working and refuse to return to the ship. Meanwhile Rygel's body fluids become explosive and Aeryn and Pilot must learn why before Rygel dies.
