Buckaroo from Powder River (1947)

Bandit Pop Ryland and his two sons, Clint and Dave, are planning their biggest job; the printing and distribution of territorial bonds. The elder Ryland contracts a hired gunman, McCall, to dispose of his stepson, Tommy, who knows what his step-family members are up to. The Durango Kid captures McCall, takes the letter and presents himself, Steve Lacey, as the hired killer. He stages a fake killing, and discovers the Ryland's scheme. Cling ambushes Durango and is killed in a gunfight, and Durango also shoots McCall who has made an escape. Cash-Register salesman Smiley Burnette aids Steve/Durango in rounding up the remaining villains.
