Lex McLean (Ian Robertson) is a young boy growing up on the rough side of late-Sixties Glasgow. His two older brothers provide him with differing role models: Alan (Joe McFadden) dreams of going to college and becoming an artist; Bobby (J.S. Duffy) roams the streets as a henchman to gang leader Charlie Sloan (Garry Sweeney). Despite having barely broken into his teens, Lex is dragged into the city's teenage underworld after he unwittingly incurs the wrath of rival gang-boss Malky (Kevin McKidd). To make matters worse for the family, Alan starts dating Malky's ex-girlfriend (Joanne Macgowan).
