Shot in black-and-white and set in San Francisco during the Gold Rush, the film combines elements of the Western genre with those of crime, melodrama and adventure. It features a wide range of actors, from hero Joel McCrea to villain Edward G. Robinson, and stars Miriam Hopkins in the leading role as Mary 'Swan' Rutledge. In an early, uncredited appearance, David Niven plays a drunken sailor being thrown out of a bar.
