Three teenage brothers, gang-member Bobby, troubled mama's boy Alan and self-assured prankster Lex, reside in a downtrodden section of Glasgow, Scotland, circa 1968. But while Bobby and Alan are beginning to experience the power of raging hormones, the story focuses on Lex, who begins a downward spiral after he accidentally shoots the leader of a rival gang. Lex's cockiness and immaturity unfortunately prevent him from understanding the effect his subsequent crimes will have on both himself, and on those around him.
