Octavia takes the damaged Nemesis ship back into space to have repairs carried out on it, taking Liz and Rudi with her as hostages. In exchange for the lives of the two humans, Fulvia demands that Adam and Shem return home with her, but the two Medusan men refuse, unless they can return to their homeworld as equals with the females. Liz and Rudi arrive on Medusa, were Rudi is put to work, while Liz is introduced to a life of luxury.

Earth hostage Dr Rudi Schmidt is forced to perform menial work, on the surface and in the city, but rebels - and other Medusan men join him. He is caught and handed over to Liz to supervise.
