Song of Arizona (1946)

Gabby Whittaker (George "Gabby" Hayes) runs the Half-a-Chance Ranch for boys from troubled homes. At the boys' graduation, Gabby's friend Roy Rogers (Roy Rogers) performs. Roy later grows concerned when one of the boys, Chip (Tommy Cook), receives a visit from his outlaw father, King Blaine (Lyle Talbot). Chased away by the sheriff, Blaine is shot and killed, leaving Chip a pawn between Blaine's gang and Roy -- who knows Blaine left the take from his last robbery with his son.
