Looking to rediscover Arizona's legendary gold mine, the Lost Dutchman, Barry Storm retraces the same steps taken by his grandfather, Jacob Walz (Glenn Ford). Having killed two men in his search, Walz became involved with Julia Thomas (Ida Lupino) and her husband, Pete (Gig Young), whose scheme to have the mine's fabulous wealth all to themselves left them -- and Walz -- dead. Now, one hundred years later, Storm is also locked in a deadly battle for the mine with a murderous sheriff's deputy (Will Geer).
