She is strong, confident, and shortly after losing the championship bout is abducted by an alien and taken to his planet. This planet has no food, water, or air. Her only means to remain alive is to marry her abductor which will allow his body to sustain hers. On his planet she is trained to fight and kill, so she can return to Earth and stop World War III before it gets started.
