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.

A scientist extracts DNA from several of Moya's crew, promising them that with it he will be able to find the locations of their home planets. Conflict arises when he asks for a sample from Pilot -- specifically, one of his arms.
