Sara Jensen is the town witch in Buck Lake, Tennessee. More than anything she misses her older brother and his best friend Reeve, who are overseas in the Marine Corps. But when her brother is killed in action, Reeve comes back with a secret—an ancient crone laid a curse on him that turns him into a ravening wolf every full moon.

Sara has a secret of her own—she's head over heels for Reeve and has been since they were kids. When he comes to her house on Halloween night asking for help, she inadvertently lays a fidelity spell on him while trying to keep him in his human form. Sara knows she must undertake the difficult and dangerous task of lifting his curse. But when the wolf within him is banished, the fidelity spell will be lifted too and his love for her will disappear.
