While this fast-paced action picture from cowboy star Tom Mix was a little lighter on the Western scenes than normal (a good portion of it takes place on a tramp steamer and in China), it otherwise has all the typical elements of Mix's work: He beats up bad guys left and right, Tony the Wonder Horse shows off a few tricks, and he doesn't get overly cozy with leading lady Claire Adams ("smushy stuff" did not appeal to Mix's youthful male fans). 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. As a result, Malvern finds himself pursued by the same men who throw him into the San Francisco bay. A tramp steamer picks him up, and he works his way across the Pacific until he lands in China, where the battle for Durant's mine picks up again. Malvern and Helen have to fight their way out of a Chinese den and make their way back to the States to claim the mine.
