Good Will Hunting

In the English class we saw this film "Good Will Hunting".
20-year-old Will Hunting of South Boston has a genius-level intellect but chooses to work as a laborer in construction and spends his free time with his friends. He also works as a janitor at the Massachusetts Institute of Technology, where Fields Medal-winning combinatorialist Professor Gerald Lambeau has posted a difficult problem taken from algebraic graph theory as a challenge for his graduate students to solve. Will solves the problem quickly and anonymously, leading Lambeau to post a much more difficult problem.
While out drinking with his friends, Will meets Skylar, a British student about to graduate from Harvard University and go on to Stanford University School of Medicine in California.
They fall in love, but he have really afraid of love.
Finally, after going out from the prison, he studies maths and solves his personal problems.
