In the very first day of their Salem vacation, Darrin and Samantha gets into serious trouble. While taking a tour of the House of the Seven Gables, a magic bedwarmer follows Samantha. The bedwarmer even follows them to their hotel room and the tour guide calls the police because she thinks that the Stephens stole the bedwarmer. Darrin gets taken to jail, leaving Samantha to get him out and to get to the bottom of this bed warmer mess.....

While Darrin sits in jail, Samantha finds out that the bedwarmer is actually a warlock trapped by one of the witches. Sure enough, the culprit is Serena. Samantha sends Serena back in time to get the spell used to transform the warlock in the first place. With one situation out of the way, Samantha faces another one- getting Darrin cleared of a crime he did not commit.
