Shank (2009)

Teenage gang member Cal hides his sexuality from his fellow happy slapping gang members' often futile and violent dislike of anyone who isn't the same as them, be they unsuspecting shoppers, foreign students, gays, etc. Hooking up with a random stranger (Scott), Cal is unaware that this chance meeting will eventually provide him with choices and routes of escape from the tedium of his unambitious and depraved life. When his world collides with Olivier, a French student he rescues from a pointless beating, he encounters a lifestyle that presents as many new experiences as it does obstacles.
