Great movie!
Will Hunting (played by Matt Damon) is a mathematical genius with a photographic memory. Shunning formal academic recognition, Will is violent and does not have any direction in his life. He gets "discovered" by this professor at the university where he is a janitor.
But being unmanageable, he gets passed on to this psychologist played by Robin Williams. He is made to discover what he wants. Of course, it ends up being: "I've got to go see about a girl" and it's Minnie Driver - his soulmate.
