Wayne is a Montana cattleman who falls in love with Dvorak on San Francisco's Barbary Coast. She helps him win a large sum of money at the gambling tables, but he then loses it to a card cheat, Schildkraut. The Duke goes back to Montana and learns cards from an ace gambler. Returning to
Frisco, he cleans up and opens his own gambling saloon. Dvorak is hired as the entertainment. The 1906 earthquake destroys Wayne's place, and, when Dvorak recovers from her injuries, they leave for Montana. A lame script that a cast of healthy actors could not put on its feet, although Schildkraut
makes a fine effort.
