Recently married Darren Stephens receives a shock when he discovers that his bride is a witch. Samantha uses her powers to get back at Darrin's condescending ex-girlfriend Sheila.

When Samantha and Darrin purchase their first home together, Samantha and Endora use their magic to see what it would be like fully furnished. But their nosy neighbour Gladys Kravitz witnesses the acts of magic and becomes shocked and hysterical.

When Darrin's alcoholic and lecherous client Rex Barker makes a pass at Samantha, she decides to teach him a lesson by turning him into a dog. The dog runs away, but Samantha eventually gets him back. When Rex makes another pass at her, Darrin knocks him cold. Rex does wind up giving Darrin his account.

Samantha has lunch with a few of her nosy neighbours, using magic to assist with the meal. Endora refers to Darrin as "What's his name", and that night at their first meeting, Darrin tells Endora that they can get along without witchcraft. They have a heated exchange before Endora leaves.

Samantha suggests clever slogans for Darrin's Caldwell Soup advertising campaign. Darrin is thrilled until he suspects Samantha of using magic to help. A fight ensues and Samantha goes home to mother. Darrin relents and pitches Sam's slogans to Caldwell. He doesn't like them either. Darrin now realises Sam didn't use any magic.
