Nia lives in Zurich's suburbia. One night Nia and his best friend Pulpo get into a gang fight because Pulpo fancies Foxy, the ex-girl-friend of rival gang leader Spirit. Pulpo is badly injured in the brawl, and Nia, who refuses to betray the other gang members, ends up in a detention centre. He soon finds himself in trouble with other inmates and obnoxious correction officers, but he also meets beautiful and tough attorney Nicole, who tries to help him. At first Nia refuses to co-operate in any way, but then Pulpo commits suicide. Seeking revenge, Nia decides to break out. He manages to escape, but instead of killing Spirit, he chooses to beat his rival in a thrilling break-dance battle. Nia's decision does not find favour with all of his fellow gang members.
