After causing a massacre on the school bus, Izzy manages to trap and imprison a couple of the bullies in the trunk of her car, showing no remorse or compassion when one of them begs to be set free.
She takes them to the barn by her home and torments them further before going inside to open Christmas presents with her little brother Kevin and Barney.
She lashes out at them, and the movie ends as it cuts back to the present to show Izzy walking away from the burning barn.
