Ruthless international crime syndicate known as the Dragon finds a buyer, evil spy by the name of Mr. Smythe, for a secret formula that enables total recall. However, they need to steal it from the US government first by kidnapping two more scientists who worked on it, the always absent-minded Dr. Olinsky and feisty microbiologist Dr. Teresa Hardgrave. Therefore, CIA Chief sends secret agent David Chase to protect Teresa. When she turns out to be a highly intelligent, self-confident and seductive sexually liberated feminist, who clicks extremely well with open-minded Chase, the two immediately hit it off after a few stimulating conversations. As they make passionate love, Dr. Olinsky is kidnapped by the Dragon's henchman and taken to their headquarters, where villainous Madame Woo shows Smythe their new technique of torture through pleasure. Victims of both sexes are sexually stimulated to the point of orgasm, but since they're unable to actually achieve it thanks to a special drug, once they reach their pleasure limit, they always break. The Dragon later kidnaps Teresa as well, but she proves to be so into sexual pleasure with both men and women that she simply can not be broken this way. In desperation, Madame Woo warns her that if she does not cooperate and give her her part of the formula, Woo's murderous boss, Y.C. Chan, will kill them both. Will Chase rescue Teresa in time and could Madame Woo actually help them?
