Moya finds herself unable to navigate an asteroid field after she shuts down to avoid detection from Crais' Command Carrier. When the crew picks up a distress call from an asteroid within the field, they explore in hopes of finding someone who can help escape. Aeryn decides to stay aboard Moya to help the Leviathan bond with her baby and keep him from inadvertently forming an alliance with the nearby Peacekeepers. Once on the asteroid, the crew discovers an environment of lush vegetation inhabited by only two life forms. The crew must decide who is the predator and who is the prey between a female, M'Lee, and a large beast, Br'nee, both claiming to be the sole survivor of a massacre at the other's hands.
