This is Your FBI - The Desert Dictator

In the Arizona desert, two older gentleman and a girl are sitting around a campfire, watching the sun go down until dark. Doctor Harold is an archeologist, Miss Larrie, is his niece, and Mason is their guide. They are in the desert to study ancient Indian culture. The three soon hear a wolf howling somewhere nearby, as their horses start to become nervous. Mason goes out to check on them, when suddenly, a stranger appears out of the darkness holding a gun. Larrie notices the stranger's arm is bleeding. He asks her for a bandage. It seems that the stranger is an escaped bandit of a bank in Flagstaff. He stole 20 thousand dollars in a running gun battle with the police. The FBI in Flagstaff was notified and Special Agent Blake drove in to confer with Sherriff Hickman.
