Three astronauts in a secret spaceship lose all contact with the ground and observe what appears to be a nuclear exchange between the USA and Russia on Earth. Two months later, the spacecraft's guidance system is mysteriously reprogrammed, forcing the crew's return to Earth.
The spacecraft lands considerably off-course, on a beach in eastern Nova Scotia, Canada. Jordan (Kate Lynch) is knocked unconscious on impact. Walker (John Walsch) exits first and is quickly killed by "terminals" – humans crazed by disease. Several hours later, in the middle of the night, Howe (Tim Choate) ventures out in search of help and a way to escape. He soon encounters Vinny (Maury Chaykin), a survivalist who has fortified his house with barbed wire and booby-traps. Vinny effectively saves him from the "terminals," and makes him his prisoner.
As the plot develops, Vinny, fellow survivor J.J. (Lenore Zann), and Howe are captured, and taken in chains to a makeshift fortress built out of junk. In order to survive, the crew must escape to the radiation-free zones while avoiding cannibal "terminals" and a sadistic military-school student-turned-despotic ruler, and escape before a malfunctioning nuclear warhead explodes in sixty hours.
