‘Sex Odyssey’ takes you into another world, past all known planets, to an undiscovered galaxy. Here, bodiless minds force victims from earth to participate in weird sexual experiments so that they can study human sexual activities. When Victor Denning arrives on this strange planet, Meliad, having been kidnapped from earth by these alien creatures, he finds that Sheila, an earth girl, has already been there for some time.

Using Sheila as a specimen, the creatures have already created some very sex-starved female bodies. The wild orgies With Victor, Sheila, and the creations are studied by the Meliads in an attempt to make male bodies with the sexual drive that they observe in Victor. After giving up all hope of escape, Victor decides that this kind of life is not so bad; girls around at all times for his pleasure; weird combinations for orgies; sex-starved women. When he is on longer of use to the Meliads, Victor is to be sent back to earth. But when the time comes, he refuses, which leads to the mind-blowing ending to the film.
