Samantha falls in love with New York ad exec Darrin Stephens and marries him in the first episode of the sitcom. Then Darrin finds out that his new bride is one of a secret society of powerful witches and warlocks and that a twitch of her nose brings magic results. Thoroughly befuddled, Darrin makes her promise never to use her powers. She agrees and tries to settle into being the perfect suburban housewife. Her mother, Endora, however, has a different agenda. She hates that Samantha has married a mortal and continually tries to break them up. Sam's other spellbinding friends and family pop in and out of the Stephens household as Sam tries (and most of the time fails) to live without magic.

Darrin is upset when Samantha reads Halloween stories to Tabitha; Samantha insists the stories are harmless; Tabitha brings the ghosts in the book to life.

Endora objects to Samantha's Halloween work for UNICEF; Darrin is turned into a hag witch by Endora.

Samantha gives a dinner party to impress one of Darrin's clients.

Gladys Kravitz is unable to convince Abner that strange things seem to be happening; Darrin meets Samantha's mother for the first time.
