Caught Bluffing.

John Oxford owns a gambling hall in an Alaskan mining town, but it known far and wide as an honest man. However, one day he finds that in order to save the life of Doris Henry, who has come to Alaska to marry Wallace Towers, he has to cheat. It turns out that Wallace has incurred huge gambling losses and is being threatened by those to whom he owes the money, and they in turn are threatening Doris--who mistakenly blames John for the predicament that she and Wallace are in.
