The Young Savages

Two Italian-American greaser (subculture)s, Danny DiPace (Stanley Kristien) and Anthony "Batman" Aposto (Neil Nephew), and the Irish-American Arthur Reardon (John Davis Chandler) are members of a street gang named the Thunderbirds in New York City in East Harlem. They have an ongoing turf war with a Puerto Ricans gang called the Horsemen. The three Thunderbirds unleash a knife attack on Roberto Escalante (José Pérez), a blind member of the Horsemen and stab him to death. They are caught and arrested, and during questioning by the police, assistant district attorney Hank Bell (Burt Lancaster) discovers one of the boys is the son of Mary diPace (Shelley Winters), an ex-girlfriend.
