In 2319, much of Earth's civilization has been wiped out and now survives in small isolated societies. In the City of Domes, citizens live idyllic lives until they turn thirty and are led to Carousel for "renewal" – but instead are killed. When Sandman Logan 5 (Gregory Harrison) dares to question the ruling order, beautiful rebel Jessica 6 (Heather Menzies) helps him escape to the outside world. Now Logan, Jessica and their android companion, Rem, are on a desperate quest for the fabled utopian Sanctuary. But with an elite police force in hot pursuit of the Runners and bizarre civilizations at every turn, death is always one step behind.
