The Young Savages

Two Italian-American greasers, Danny diPace and Anthony "Batman" Aposto (Neil Nephew), and the Irish-American Arthur Reardon 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 Rican gang called the Horsemen. The three Thunderbirds unleash a knife attack on Roberto Escalante, 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 discovers one of the boys is the son of Mary diPace, an ex-girlfriend.
