400 Years Later

400 years ago to the day the end of a biological war killed the last of the human race on Earth. That same day, 1000 teenagers were sent into space and cryogenically frozen, so that one day, they could return to the post-apocalyptic world that used to be Earth, and maybe, just maybe, have the chance to start the human race again on a new Earth. But they don't what they might find, and they certainly won't be alone.
