The USC Westbound carries the last remaining survivors of the human race. After nearly twenty years searching for a new home or signs of intelligent life, an incurable virus spreads on the ship and threatens to kill mankind once and for all. In a desperate attempt to save the human species, two immune teenagers are put into cryostasis and sent into deep space. When they finally awaken, the sins of mankind's past haunt them and threaten, one way or another, to kill them both and forever close the chapter on our existence.
