Free Money (1998)

The Swede, a prison warden, rules his family and his prison with an iron hand in one of the coldest parts of North Dakota. When an inmate dies under mysterious circumstances, however, the FBI sends in agent Karen Polarski to investigate. On the home front, the sons-in-law of the Swede, Larry and Bud accidentally discover that a train loaded with millions of dollars of unmarked currency slated to be destroyed will soon be passing through. The temptation is too great and the guys hatch a scheme to rob the train. Of course, the biggest obstacle in their way is the Swede.
