Not Just Another Woman is the story of an oversexed, young handsome and rich playboy whose beautiful wife seduces other young beautiful women and brings them home to feed her husband's ego.

She is willing to bring him any woman in the world but one-her younger sister, a bride of Christ and the one woman desired by the husband most.

He becomes so obsessed with this desire for his sister-in-law that his fantasies soar to an uncontrollable height. The conclusion of the film finds him so completely inundated in one of his fantasies, he ends up at the bottom of a cliff in a flaming Mercedes Benz.
