PlotWhen big-shot professor Lambeau ( Stellan Skarsgard) presents a math challenge to his students, with a fine reward to match, Will(Matt Damon) anonymously solves the formula on a blackboard placed in the school's corridor. Lambeau begins a search for the mysterious student, and upon finding Will takes him under his wing. It's the only way for Will to get parole after a number of run-ins with the law. Lambeau makes two conditions: that Will meet with him once a week for a math session and that he begin therapy.
A succession of psychologists tries to reach Will, using various techniques (including hypnosis), but he won't cooperate. Finally, Lambeau summons his old, alienated classmate, Sean McGuire (Robin Williams), a community college instructor and therapist --- and the real drama begins.
Most of the narrative consists of intense one-on-one sessions between Will and Sean, two equally stubborn, equally wounded men. ``Good Will Hunting'' becomes a poignant, embracing drama of hurt, scared humanity learning to reach out. The outcome of the movie is fairly predictable; so is the whole story, really. But meeting expectations and following a familiar path aren't always bad things in a movie, provided the film accomplishes those goals with a infinite amount of style and an attention to detail. Good Will Hunting does both.
