The film is set in the late 1930s, during the Second Sino-Japanese War. In the first scene, Lieutenant Kurokawa scourges, rapes and disembowels Chinese people during the war. Later, he returns home as a war hero, but with a horribly mutilated body. He is alive but reduced to a torso (no limbs), deaf and mute, with burns covering half of his face, but with three medals on his chest. Despite his condition, he is still constantly eager for sex, which he performs acrobatically with his wife. The sexual acts are rough and are imposed on his wife, who is repelled by him, but who nevertheless feels a duty to take care of him. The film concludes with the disabled veteran Kurokawa committing suicide by dragging himself into a pond outside his home.
