When the police arrive at Samantha and Darrin's hotel room, Darrin takes the fall for Samantha in the alleged theft of the bed warmer from the historic site, the House of the Seven Gables. While Darrin is locked in jail awaiting his court appearance, Samantha is free to discover who, using witchcraft, turned a warlock into that bed warmer during the Salem witch hunts. She figures the best way is to use the fact of the witches' convocation taking place to survey the general populace, with a little extra help from Endora. When Samantha discovers the who, she comes to understand why the warlock behind the bed warmer has such an interest in her. That warlock is named Newton, who has a one track mind, namely the pursuit of the opposite sex, most specifically the witch that turned him into the bed warmer. As that witch only allows Samantha to free Newton from his bed warmer prison on the condition that Newton not contact her, Samantha has to redirect Newton's energies toward someone else ultimately to get Darrin off on all charges.
