Will Hunting is a brilliant but troubled young man from South Boston who works as a janitor at MIT and secretly solves graduate-level math problems on hallway chalkboards. After an assault charge threatens to send him to jail, Professor Gerald Lambeau arranges a deal: Will can avoid prison if he studies mathematics and attends therapy. Most therapists cannot get through his defenses, but Sean Maguire, a grieving psychologist with his own scars, refuses to play Will’s games. As Will falls for Skylar and leans on his loyal friends, he must decide whether to keep hiding behind talent and anger or risk building a life beyond the pain that shaped him.
