Hidden Loot (1926)

Anna Jones, racing her brother Dick to their ranch, is "rescued" from her fast horse by a stranger (Cranner) whom she indignantly brands a bonehead before riding away. "Big Bill," a ranch employee, steals the payroll bag and joins his gang in the forest, where the stranger sees them hiding the bag in a shack. He investigates and is captured by the gang. His dog, Bunk, however, leaps through a window with the loot, buries it, then returns, frees Cranner by digging a hole under the wall, and keeps the bandits at bay while Cranner escapes. Anna encounters Cranner, and though she believes him guilty, she is so impressed by his gallantry that she falls in love with him and helps him evade Bill and his gang. Cranner follows Anna and rescues her from the clutches of Bill; then the posse arrives, and Anna discovers that the stranger is actually a Texas Ranger.
