Trail Riders(1942)

In the 18th entry of Monogram's 24 "Range Buster" films, the bank of Gila Springs is robbed by Ace Alton and his gang, and Sheriff Frank Hammond, son of Marshal Jim Hammond, is killed. The Marshal sends for the Range Busters, Dusty King, Davy Sharpe and Alibi Terhune, to come and restore order to the town. Ed Cole, head of the local vigilantes, and secretly the head of the outlaws, promptly orders the trio out of town. They visit an old friend, Rancher Mike Rand and his daughter Mary. Mary's brother Jeff has unwittingly become a gang member, and carries out Cole's orders by taking a shot at Davy, but the latter makes him a prisoner during a subsequent fight in the town café. Jeff confesses to Cole's involvement, and the Range Busters, with the help of town banker Harrison, set a trap for Cole and his outlaw vigilantes.
