During routine searches for Peacekeeper beacons, D'Argo falls down a chute, destroys a Peacekeeper shield and gets ejected into open space. After being rescued D'Argo starts to think that everyone on Moya are members of his family. Moya, meanwhile, starts to alter the environmental conditions inside the ship so that it is hardly habitable for the crew.

While taking a piloting lesson on a transport pod with Aeryn, Crichton gets caught in an energy field which is invisible to their sensors. Meanwhile, back on Moya, a strange guest docks and comes aboard to warn the crew about The Flax, an invisible energy net created to catch ships which are then plundered by pirates.
