Where can I watch this?

After being wrongfully expelled from Harvard University, American Matt Buckner flees to his sister's home in England. Once there, he is befriended by her charming and dangerous brother-in-law, Pete Dunham, and introduced to the underworld of British football hooliganism. Matt learns to stand his ground through a friendship that develops against the backdrop of this secret and often violent world. 'Green Street Hooligans' is a story of loyalty, trust and the sometimes brutal consequences of living close to the edge.
