The Lexx travels to Earth looking for food. It is located in the very center of the Dark Universe and the crew assumes that it must be a very dangerous place. The crew again meet people they knew from the Light Universe, and from Fire and Water. Only Prince and Priest are able to remember their lives on Fire.

The Earth is threatened by a being who resembles Lyekka. The crew finds out that the fake "Lyekka" destroyed all human life on her way through the Dark Zone. Kai decides to destroy the asteroid that is the source of the entity. Prince keeps his promise and restores Kai's mortality.
