City Across the River(1949)

Brooklyn youth Frank Cusack, good son and brother by day, is a gang member by night. The Dukes, seemingly likable dead-end-kids, are dangerously involved with racketeer Gaggsy Steens. Despite the efforts of Franks's parents, he and pal Benny get involved in a serious crime. Can Stan Albert, head of the community center, prevent them from becoming full-time crooks?
