Every spring the fur trappers make their way to the fort determined to drink and gamble themselves into oblivion. Lady Hammond begs Blackfly to stop Colonel Boyle from gambling with them. Blackfly does as she asks but it's Lady Hammond herself that succumbs to the ""Boyle Curse"". To save Lady Hammond, now deep in debt to the trappers, Blackfly calls on an old acquaintance, Stateside Bobby, an unsavory gambler. Stateside fleeces the trappers and frees Lady Hammond but what he wants in return may be too much to pay.
