Kimble figures out that Rachel is in fact Joyce, the other school teacher he has developed a crush on, and Dominic (his favourite student) is the son of his enemy.
Crisp the murderer tracks them down and shows up to the school with his mother (complete with bride of Frankenstein type hairstyle). He starts a fire in the library, and while everyone is evacuating he kidnaps Dominic. Kimble tracks him through the corridors. Meanwhile, the bride of Frankenstein spies Phoebe outside and knocks her down with the car.
Rachel screams when she finds Crisp & Dominic, and is knocked unconscious by the bad guy. Arnie corners them in the locker room, but the ferret that was hiding in Dominic's jumper bites Crisp on the hand allowing Dominic to get away. Kimble shoots Crisp dead.
The old mother shows up and shoots Kimble through the shoulder. He crawls away. She sees her dead son, and then goes after Kimble teasing him with some shots close to his head. Just as she is about to finish him off, Phoebe shows up with baseball bat, knocks her senseless and then says "Not too tough without your car, are ya?"
Kimble is in hospital recovering, when he is visited by Phoebe and her chef boyfriend.
Later he returns to the school, the kids love him, and Rachel leaves her class to run into his arms.
