本影集改编自吉儿·墨菲广受欢迎的书作，描述一名笨笨的女主角在阴差阳错下进入女巫学校就读后，意识到自己可能属于那里。

Great adventures can hatch from the smallest eggs. Fucsia wants to learn to do magic just like her father, and so is pleased as punch when she is allowed to go to witches' school. There, Fucsia learns to make wind and conjures with the clouds. But her magic often has unexpected results, however, as she is sometimes that little bit too ambitious.

凯丽（玛丽-凯特·奥尔森 Mary-Kate Olsen 饰）和林恩（艾什丽·奥尔森 Ashley Olsen 饰）是一对出生在贫穷家庭里的孪生姐妹，他们的爸爸妈妈陷入了重重的债务危机之中，如果无法筹得欠款，那么他们就将要失去他们赖以生存的家。 无奈之下，夫妻两人决定向残暴的阿加莎借钱。阿加莎有一个名叫索菲亚的双胞胎姐姐，她用自己无意之中得到的拥有强大魔力的月亮宝石，将索菲亚封印在了一面镜子里。如果索菲亚不能够在70年内找到从镜子里出去的方法，那么她就将被永远的困在其中。想要打破魔咒，需要一对双胞胎在镜子前面说出规定的咒语，得知此事，凯利和林恩决定结伴而行，踏上了解救善良的索菲亚的旅途。

小女巫只有 127 岁，对于一年一度的女巫集会来说还太小。虽然她的年龄还不足以成为一名真正的女巫，但她想成为一名真正的好女巫。这个决定给她的魔法世界带来了麻烦。

碧碧（西多尼·凡·克罗斯克 Sidonie von Krosigk 饰）是一个活泼可爱又善良正直的小巫女，因为用魔法做了好事，魔法协会决定提前给碧碧举办成人礼，这也就意味着，碧碧能够早一步的拿到可以看到过去和预知未来的魔法水晶球。然而，邪恶的女巫拉比亚（科琳娜·哈弗奇 Corinna Harfouch 饰）故意摔坏了碧碧的水晶球，为了惩罚拉比亚，魔法协会将拉比亚的水晶球给了碧碧。 失去了水晶球，拉比亚感到非常的愤怒，她制定了一个邪恶的计划，不仅要夺回属于自己的东西，还要将碧碧一家人永远的赶出魔法界。不幸的是，拉比亚的阴谋诡计成功了，但在最后的节骨眼上，碧碧还是识破了她的骗局。

碧碧（西多尼·凡·克罗斯克 Sidonie von Krosigk 饰）因为成绩不好而被送入了位于阿尔贝尔宫的辅导学校，在那里，她认识了坐在轮椅上的女孩艾丽娅（Marie-Louise Stahl 饰），很快，两个小姑娘之间就结下了深厚的友谊。与此同时，因为碧碧而被关在沼泽牢笼里的坏巫女拉比亚（科琳娜·哈弗奇 Corinna Harfouch 饰）越狱成功，怒火中烧的她唯一想做的事情就是向害她如此之惨的碧碧一家人寻仇，而此时的碧碧对这些还一无所知。 碧碧唯一关心的事情，就是如何能够让艾丽娅重新站起来，她得知有一种能够治愈一切疾病的魔法药物名叫蓝色猫头鹰粉末，于是，碧碧和艾丽娅一起踏上了旅途。

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.

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.

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.
