Sabrina's senior year didn't start out as planned, and as a result, she decides to move in with her father and his new family in Paris. However, it doesn't take long for Sabrina to realize how much she misses her family and friends in Westbridge that she changes her mind and moves back home.

Sabrina learns that she has to spend the year mentoring a witch who doesn't have a good grasp on her magic – or lose her witch's license. Things are going as well as expected until Dreama's clumsy spell casting causes Brad to become suspicious of Sabrina and her odd new friend.
