Based on a novel by Pier Paolo Pasolini, UNA VITA VIOLENTA chronicles the life and death of Tommaso (Franco Citti), a street kid who is equally comfortable running with the Fascists, the Communists and just plain thieves. Tommaso's milieu is the filthy slums outside Rome; his occupation is whatever comes to hand to make a few bucks, until a stretch in prison convinces him to go straight.
This extremely obscure Italian production tells the story of a modern day neo-Nazi youth gang that meets in a place decorated with swasticas and a poster of the "Führer". The members of this gang are all bored teenagers from rich families. One of the gang prefers playing pin pall to getting a girlfriend, because playing pin ball literally gets him off. The leader of the gang indulges in violent sexual fantasies, which ultimately leads to rape and murder. This inspires a teen gang from the streets, whose members are poor kids from the ghetto.
