Yellowstone

Ranger Dick Sherwood (Henry Hunter) patrols Yellowstone National Park, where he runs into beautiful Ruth Foster (Judith Barrett), who is there to meet her absent father for the first time. Old Pete (Raymond Hatton), a Yellowstone regular, tells the pair a tale of three gangsters who hid money in the park decades ago. Then Ruth's father, who turns out to be one of the mobsters, is found murdered. Dick and Ruth try to find the killer while also scavenging the park for the hidden money.
