A young-looking witch named Samantha (Elizabeth Montgomery) meets and marries a mortal named Darrin Stephens (originally Dick York, later Dick Sargent). While Samantha pledges to forsake her powers and become a typical suburban housewife, her magical family disapproves of the mixed marriage and frequently interferes in the couple's lives. Episodes often begin with Darrin becoming the victim of a spell, the effects of which wreak havoc with mortals such as his boss, clients, parents, and neighbors. By the epilogue, however, Darrin and Samantha most often embrace, having overcome the devious elements that failed to separate them.
Darrin works for the advertising agency, McMann and Tate. He is the deuteragonist of the show.
Samantha's mother, Endora loathes mortals, and disapproves of Darrin, as do many of Samantha's relatives. Endora refuses to even use Darrin's name, alternatively calling him "Durwood", "What's-his-name", "Darwin", "Dum-Dum", etc., all much to his annoyance. She refers to him as "Darrin" only eight times during the entire series. Endora casts countless farcical spells on Darrin, but never attempts to destroy him outright. Endora's ploys to provoke a breakup always fail as Samantha and Darrin's love overcomes every obstacle. When High Priestess Hephzibah expresses surprise that Darrin has withstood years of harassment, Endora can only shrug and admit, "He loves my daughter."
