Eva, a hermaphrodite from birth, with clear signs of both sexes, is raised under the strict guidance of her uncle, Professor Pissinger. The professor surgically implants a device called a "sexmaker" which allows Eva to control her sexual intensity. Unfortunately, this also puts her in the sights of an impotent gangster who wants the device for himself.
