The intrepid Jacky Faber, having once again eluded British authorities, heads west, hoping that no one will recognise her in the wilds of America. There she tricks the tall-tale hero Mike Fink out of his flatboat, equips it as a floating casino-showboat, and heads south to New Orleans, battling murderous bandits, British soldiers, and other scoundrels along the way. Will Jacky's carelessness and impulsive actions ultimately cause her beloved Jaimy to be left in her wake?
