sports and violence

At firt sight, the film seems that it was about football and violence that do the gang of dangerous supporters of it. However, when you are in the film you can see that it means to say something more. In spite of all the violence, it has got deep feelings of friendship, pride and brotherhood that we can appreciate.
The argument:
First we can see a boy who starts to go with a group of Holligans, after being unfairly expelled from Harvard university because of helping another student. Step by step he begins going out and taking part in this dangerous world. He usually takes part in the struggles and fihts in the street and finally he is very keen on taking part in all of them.
As a consequence of the firm, they hurt Stephen and also their pride so they will have a very violent struggle when Pete died.
Eventually, Mate comes back to Harvard university where he will have to forz the student to confess, that it was him the one who had the some cocaine in his possession.
