American Damsel (Melody Marks) has been taken captive by her arch-nemesis Nightmare, who's subjected her to a horrifying bad dream. American Damsel wakes up, but now her nightmare continues in real life. Her captor has dressed her up in her patriotic crimefighting costume of bikini, gloves and boots, and she's tapegagged and tied down to a table — with a powerful vibrator secured between her thighs. Nightmare enters and explains that it's a unique vibrator, and it will cause a dramatic and irreversible change to her DNA as soon as she orgasms. The heartless villain then switches on the evil device and the helpless super-lady tries her best to resist the seductive hum and free herself. But there's no escape for her, and before long she succumbs to an ineluctable, helpless orgasm.
