The Battle For Earth - The Challenge

In a confrontation, three villains challenge a heroine to a fight, betting that if she loses, they can do as they wish with her. Overconfident, she underestimates their plan, which involves draining her energy by forcing her to exert herself for several days while they enhance their own abilities with a serum. When she finally engages in battle, she is too fatigued to compete against her three opponents. Consequently, they fulfill their promise of doing whatever they desire with her, highlighting the repercussions of her earlier arrogance.
