Sabrina Spellman, a perfectly normal 16-year-old, is informed by her aunts, Hilda and Zelda, that she (and they, and her whole family on her father's side) are witches. She lives with them in Massachusetts while preparing to receive her witch's license. Along the way, she gets into many scrapes while figuring out how certain spells work. She also has to keep the secret from her boyfriend, Harvey, friends Jenny and later Valerie, stuck-up nemesis Libby, and her ever-suspicious vice-principal, Mr. Kraft.

Morgan submits Sabrina's article to a contest and she lands a job at Scorch magazine. Zelda and Hilda move back to the Other Realm and Sabrina and friends move into their house.

It's a day for celebration when Sabrina finally receives notice that she has earned her Witches License. Before the Other Realm ceremony the next day, however, she has a few mortal concerns with which to deal. First, Mr. Kraft has assigned her to pick the theme for the school dance. Second, Harvey and Dashiell are pressuring her to choose between them once and for all. Promised that her license will bring her all the knowledge in the universe, Sabrina puts off her decisions and attends her party in the Other Realm. She is presented with her license, but Hilda and Zelda explain there's a catch. Before she can use it, she must uncover her family secret, and family members will be visiting her periodically to act as her guides. Sabrina is desperate to solve her romantic dilemma, so she turns to her magic book for a spell that will reveal her heart's desire. The next day, Harvey and Dashiell come to school dressed as cowboys and ready for a showdown.

All of Sabrina's responsibilities as student, girlfriend and witch pile up on her as she fails her witch's exam and ends up at witch boot camp.

Sabrina goes to live with her father in Paris.

Sabrina and Miles decide to produce a horror picture and some of the actors may be real monsters.
