American astronaut John Crichton, along with his shipmates aboard the sentient spacecraft Moya — Aeryn Sun, D'Argo, Rygel, Zhaan, and Chiana — arrive in a system inhabited by two different civilizations. Desperate for supplies, Crichton, Zhaan, and Chiana land on the Kylei, a tropical planet populated by a spiritual society. Meanwhile, Aeryn, D'Argo, and Rygel go to Garangee, a rocky planet with hard, industrious people.
The Kylei and the Garangee have been at war over a third world, Tivara. Both claim it is their holy land, a place where infinite knowledge can be gained, knowledge that Crichton and company must have. Moya's crew must tread a delicate path to avoid fanning the flames of war between the two opposing civilizations, while attempting to gain access to the information that could lead the travel-weary crew back to their homes.
