Number 7

A man named Shichiro was placed into hibernation in 1961 by his father to avoid a predicted nuclear war. He awakens in 2061 at the base of a mountain. Humanity now resides in space and seeks to reclaim Earth. After being rescued, he learns he is one of only seven people immune to the effects of hydrogen bombs. This immunity makes him valuable in efforts to return to Earth. He uses some of his father's inventions and works with the other six immune individuals to help achieve this goal.
