The evil symbol "King Joker" was planning to destroy America using comet missiles, prompting a lone superheroine from the U.S., Wonder Girl, to come to Japan to stop him. However, she falls victim to Japan's sadistic torture techniques. Combatants wearing special punch gloves pummel her with relentless belly punches, metal wires choke her neck, and she's pulled from both hands while taking brutal body blows. She endures further torment with electric shocks and harsh whip lashes, her body twisted by dark magic as mysterious fluids are smeared onto sensitive areas. Writhing in unbearable itching, Wonder Girl gradually becomes incapacitated. Then appears Mr. Beast, a Black combatant possessing the same powers, who overwhelms her with even more devastating attacks. In the end, was Wonder Girl truly unable to win any of these battles?
