Sarah is a young housewife whose sex life is slowly disappearing, so she decides to find a job in order to pass the time. She reads an ad in the paper offering an apprenticeship for an exciting job, but she doesn’t realize until she meets Jamie that the apprenticeship is for witchcraft. Jamie confesses that she is a witch and that she only dabbles in sexual magic. Sarah, although skeptical, accepts the offer to become a witch’s apprentice and begins to learn how to use the various spells Jamie teaches her, especially one she hopes to use to get her sex life back on track with her husband, Michael.

As Sarah learns more magic, she becomes convinced that she is a better witch than Jamie. The two decide on a contest in which the first one to make their new neighbor, George, fall in love with them, without using magic, wins. Sarah in her desperation uses magic to cheat and win George’s affection while possessing Jamie. George, unfortunately for both of them, turns out to be a warlock looking to destroy all witches by draining their powers through sex. Jamie and Sarah resolve their differences and defeat the warlock together.
