Samantha, her friends, Bertha and Mary, and her Aunt Clara, all witches, decide to change the popular conception of witches into a more flattering image. Their opportunity arises when Darrin, an ad man, is assigned to devise a trademark for a new type of Halloween candy. Mr. Brinkman, the promoter of the candy, wants the trademark to show a traditional witch. Darrin at first agrees, but when he sees how upset Samantha becomes, he decides to present a beautiful witch. Mr. Brinkman objects, but Darrin refuses to yield. Consequently, he is fired. The witches decide to practice some of their pranks on Mr. Brinkman. As a topper, they transform him into an ugly old witch. Mr. Brinkman finally admits that his idea of witches is wrong. He agrees to use a glamorous witch for his trademark. Samantha wins her point, and Darrin wins back his job.

Samantha's Aunt Clara arrives on the Stephens' first anniversary with presents for Samantha and Darrin. Casting a spell to adjust a checkered cap she has given Darrin, Aunt Clara uses the wrong words and turns Darrin into a chimpanzee. Unable to remember how to remove the spell, Aunt Clara goes home to look for the formula.

Darrin's parents pay their first visit to the Stephens home, Darrin's mother, Phyllis, hopes to find that his wife is a poor housekeeper. Soon after, Samantha's Aunt Clara comes down the chimney for an unexpected visit. Darrin is worried about the kind of impression Aunt Clara will make on his parents, but agrees with Samantha that they must make Aunt Clara feel welcome. Determined to help Samantha make a hit with her in-laws, Aunt Clara uses her witchcraft to whip up a feast for dinner. Thinking that Samantha has done the cooking, Phyllis becomes quite upset. Although Samantha warns him to be tactful, Darrin makes Aunt Clara feel she is not wanted. After Aunt Clara's de-parture, Samantha gets into an argument with Darrin, during which Phyllis learns Aunt Clara cooked the dinner. When Samantha admits she is not a good housekeeper, Phyllis, who felt she was being pushed aside, knows she is going to love her daughter-in-law. Darrin persuades Aunt Clare to return and the evening ends happily for all.

When strange things begin happening to Adam Newlarkin, a friend of Darrin's, Aunt Clara tells Samantha he has inherited the spell placed by a witch on his ancestor who was a judge in Salem two hundred years before. Aunt Clara adds that unless Adam follows the antidote for the spell strictly, he will be branded a thief. The Stephens learn that Adam has been hired by a local bank. Samantha and Darrin manage to get Adam to kiss a dog, the first step. With Aunt Clara's help, Darrin dunks Adam in a pool three times. They have trouble persuading him to ride through town shouting praise of witches, which is the final step.

Larry Tate invites Samantha and Darrin to a buffet for prospective client Charles Barlow. When they complain about the condition of their clothes, Aunt Clara uses magic to produce a dress for Samantha and a new suit for Darrin, who invites her along to the affair. Once there, Aunt Clara removes a fire hydrant so Darrin can park. At the party, Samantha?s dress begins to vanish and Aunt Clara's other magical efforts begin to disintegrate.
