Two former Siamese twins - Q and Grossfinger - are the respective leaders of good and evil. The evil Grossfinger sends agent Ken Starbuck to seduce call girl Luciana and recruit her into their sinister organization. She agrees to let doctors implant an atomic device in her vagina, a device which will suck the brains of the johns into a tiny computer while they climax. Meanwhile, Q finds out about the sinister plot and sends Commander James to resolve the situation with the help of a special decoder.
