The young executive of an advertisement agency, Darrin Stephens marries a beautiful woman, Samantha Stephens. On their honeymoon, Sam discloses a secret to him: she is a witch with magic powers. He makes her promise him that she will live like a mortal, without using witchcraft and spells in their lives, but sometimes she uses her magic to help Darrin and herself. Sam’s mother, Endora does not accept her mortal son-in-law, hates him and can hardly say his name correctly. In the suburb of Westport, Connecticut in the street of Morning Glory Circle, where they live, their curious next-door neighbor Gladys Kravitz suspect Samantha, but can never prove the weird situations she sees to her husband Abner Kravitz. Darrin works in the McMahon and Tate ad agency with Larry Tate, who is married to Louise Tate. Samantha frequently receives her witch aunts in her house, specially her sweet old Aunt Clara.
