It is 2055 and the post-apocalyptic world is populated exclusively by women; all the men were killed in the Great War and the scourge that followed. Into this matriarchy comes Major Jason Mercer, who was cryogenically frozen forty years earlier and now awakened in Lithia. Lithia is a small agricultural enclave overseen by a group of women that include the regal elder, Hera, Ariel, Miranda, and Pele. Mercer's arrival sparks a debate about the nature of men among some women and revives long-dormant sexual feelings in others. The debate intensifies as Mercer, seeing the enclave's poverty and primitive tools, begins to repair the community's broken machines and pushes Miranda, the group's trade representative to barter with Hyacinth, a neighboring community, for electricity to run the machines. Over the objections of the elders, Mercer gets the machines running by stealing power from Hyacinth's dam. But, can Mercer revive the world of men without also bringing back the violence, anger, and death which led to his gender's extinction?
