When an elderly, wealthy man decides that nuclear holocaust is eminent in his country, he decides to move his family to Brazil at all costs--a place which, for some mysterious reason, he believes to be safe. His family refuses to move because they fear that the move will jeopardize their financial well-being. Nakajima burns down his foundry to force them to go to Brazil but, instead, they go to the courts and have him declared mentally incompetent. After several more increasingly irrational acts, he is finally placed in a mental asylum, where he sits staring at the sun, believing that he is on another planet and the sun is the raging inferno created by the Earth when it went up in the nuclear holocaust--vindicating his actions. A strong indictment against the inherent evils of nuclear warfare, it is also the story of a man's love and dedication to his family in the face of his own fears and endangerment.
