Ice Harding, outlaw, tames a wild horse and names it King. Ice and his gang hold up a stagecoach and encounter San Francisco vice king Bates and his innocent niece Betty Werdin. Ice is taken with the young woman, but at first she sees nothing in him. But she begins to come around when her uncle tries to swindle Ice, and the outlaw himself undergoes a change of course under the influence of the girl.
