Dr. Karl Sternau (Lex Barker) is a German doctor in Mexico who is on the side of the Mexicans fighting against Emperor Maximillian and the French occupation. With the help of the clock dealer Andre (Ralf Wolter), Karl tries to stop a gang led by the villainous Captain Verjoda (Rik Battaglia) from stealing an ancient Aztec treasure. Wolter provides the comedy relief in this routine adventure drama. ~ Dan Pavlides, Rovi
