A warlock refuses to use his powers for evil, but comes across another warlock who isn't bothered by such trivial matters. In fact, the evil warlock falls for the good warlock's girlfriend, and decides to get rid of his competition so he can turn the girlfriend into one of his many sex slaves. The good warlock, not quite sure how to handle the situation, turns to an African witch doctor for help.
