Shy and quiet Amanda Santorelli is unhappy watching the world go by around her. When her well-meaning but wacky aunt casts an assertiveness spell on her, Amanda's orderly world is turned upside down. Unable to control herself, Amanda blurts out whatever is on her mind every time someone asks her a question. Trying to outwit the spell only makes matters worse. With no control over her own mouth, it's only a matter of time before someone discovers the object of her secret obsession.

Mark Abbott is happy with the way his unassuming assistant runs his office. But all of a sudden she's become a new person—both in attitude and appearance—and he's not sure he likes the effect on his orderly work routine. With each passing day, he finds himself waiting to see what will come out of her mouth next. Before long, he can no longer deny the truth—the new Amanda is seriously making him reconsider his vow never to mix business with pleasure.

Mark doesn't know if it's love—or if he's just a victim of Hocus Pocus.
