The show chronicles the adventures of Sabrina Spellman, a girl who discovers on her sixteenth birthday that she is a witch. As a novice witch, her spells often go awry. Hilda and Zelda Spellman, her aunts, counsel her on the proper use of her magic and give her moral advice. Additionally, Hilda and Zelda must take care of Salem Saberhagen, a warlock turned into a cat for trying to take over the world. Sabrina's basic premise and "genial loopiness" earned the show comparisons to the 1960s television series Bewitched.
