Swede's twins tell their father they're pregnant (they aren't), so he pushes their dim boyfriends, Bud and Larry, into shotgun marriages. He also turns his sons-in-law into slave labor, so Bud hatches an escape plan: to rob a train carrying old bills to the mint for burning. Larry's his reluctant accomplice. When Bud is captured and railroaded into Swede's jail, his death looks certain, until he hatches yet another plan that requires Larry's help.
