Flung through a cosmic wormhole, American astronaut John Crichton finds himself fighting for his life in the middle of an alien prison break, inside a Leviathan a living space ship on the far side of the galaxy. Hunted by the relentless Crais, a commander of the galactic enforcers known as Peacekeepers, Crichton joins forces with the alien convicts hulking warrior Ka DArgo; blue-skinned Priestess Zhaan; diminutive Dominar Rigel XVI; the giant symbiote Pilot and the irreversibly contaminated Peacekeeper Aeryn Sun. Each desperately seeks a way home, but first, they have to find a way to trust one another. Daring escapes and selfless acts of courage forge a measure of loyalty, friendship and even love. The first seasons breakneck action heats up with the introduction of the coquettish thief Chiana and the sinister Scorpius with his dreaded Aurora Chair. Arrival and departure, birth and death, rescue and betrayal, all lead up to a season finale cliffhanger that is, literally and figuratively, breathtaking.
