chunk: The next day as Will and his friends fight a gang at the basketball court, Police arrive and arrest Will. Lambeau visits his court appearance and notices Will's intellect in defending himself. He arranges for him to forgo jail time if he agrees to study mathematics under Lambeau's supervision and participate in therapy sessions. Will tentatively agrees, but treats his first few therapists with contempt and mockery. His refusal to open up is met with staunch defiance by the various therapists, who each refuse to deal with Will further. In desperation, Lambeau calls on Dr. Sean Maguire (Robin Williams), his estranged and much more grounded college roommate, who now teaches psychology at Bunker Hill Community College. Unlike other therapists, Sean actually challenges Will's defense mechanisms, and after a few unproductive sessions, Will begins to open up.
