Determined to avoid the villainous Scorpius' pursuit after the destruction of the Peacekeeper Gammak base, Moya - the sentient Leviathan spaceship that serves as home and transport for Crichton, Aeryn, D'Argo, and the rest of the crew - is forced to abandon her newborn offspring, Talyn, to the devious Peacekeeper Crais so that she and her crew can safely navigate the Uncharted Territories of space. As they traverse the galaxy in their quest for a way to their respective home worlds, Moya's crew must deal with the consequences of her decision, as well as encounter many hostile aliens and the dangers they present.
