Ambush Trail

Supply wagons are being ambushed and the town's sheriff is missing. Curley Thompson finds the sheriff's pearl-handled pistol after his own wagons are attacked.

Fearing the sheriff has been murdered, he enlists the aid of a local rancher. When the rancher is shot in the back, Curley is framed for his murder. It's up to him to find the real killer before the federal marshals track him down.
