As he was being arrested by detective Negoro, the detective's bullet struck Sakuko, Yamabe's girl friend who attempted to protect him, and crippled her. When Yamabe was sent to prison, Negoro cared for her and they fell in love. Sakuko asked him to marry her, but Negoro was reluctant to take the killer's sweetheart from him. Learning of the relationship of his girl friend and the detective, Yamabe had pledged revenge.
