When a member of the North-West Mounted Police, robs the First National Bank in Bismark, North Dakota, inadvertently killing the bank manager in the process, the chase is on. The bank happens to be owned by Canadian James J. Hill, a real-life millionaire and the model for the Great Gatsby. Hill's used to getting what he wants and keeping what he has. So when he loses his Great Northern payroll in Bismark, what he most wants is for the vicious William Pinkerton and his sleazy henchman Jiggs Dubois to bring him the head of the varmint that took it.
