Naive Montana cowboy Duke Fergus arrives in San Francisco and visits the notorious Barbary Coast. Fergus becomes smitten with the lovely star attraction of the fanciest gambling hall, "Flaxen" Tarry, the "Flame of the Barbary Coast". Fergus gets talked into gambling against the owner (and Flaxen's lover), card shark Tito Morell. Predictably, Fergus gets cheated and loses all his money.
Fergus sets himself to win Flaxen's affections and decides the best way to do it is to take over. Fergus gets his friend Wolf Wylie to teach him everything about gambling, including how to spot cheating. When Duke's ready, he sells all he owns and returns to the city to challenge Morell's rule of the Barbary Coast. He goes from casino to casino, challenging each one's resident poker champion to a heads-up game, starting with Morell. Duke wins every time.
Fergus then builds an opulent new gambling establishment, catering to the upper class. To make it a success, he needs to persuade Flaxen to come work for him, but she is initially not interested. Only when Morell offends her does she decide to accept Fergus' offer. On opening night of the new establishment, Morell comes to challenge Fergus and win back Flaxen only in the midst of it all, a great earthquake hits, leaving Fergus' and Morell's businesses destroyed and Flaxen grievously injured. The town rebuilds and Fergus helps Flaxen in her recovery.
In the aftermath, both Fergus and Morell run for mayor. Fergus catches Morell's men in the act of trying to rig the election. Fergus turns the results over the people to have them decide in favor of returning to Montana to marry Flaxen, while Morell keeps his business and influence.
