Mix is Grant Malvern, a rancher who befriends scientist Quentin Durant (Tom S. Guise) after rescuing him from a trio of Chinese crooks. The crooks want to find Durant's Arizona gold mine, and the map to the location is contained in a pair of rings. After the crooks track down Durant and kill him, one of the rings winds up with Durant's daughter, Helen (Adams), and the other falls into Malvern's hands.
