A group of four siblings reunite in Glasgow on the eve of their mother's funeral, and the children mourn their mother's passing in a variety of ways—sometimes heartfelt, sometimes bizarre. As a potential thunderstorm threatens to damage the city, the situation compounds itself.

Jerry and Gordy are white trash hoodlums surfing into adulthood as their factory town school closes for the summer. But their teenage daydreams turn sour when the test of friendship and the ties that bind transform an innocent quest for freedom into a baptism of fire.

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 Bobby's 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.
