 Graft is rampant in the government of a "mythical" Louisiana, and the arrival of U.S. Senate investigator Loganberry brings panic. The chief miscreants shift the blame on to their innocent tool, Jim Taylor, who to save himself must "compromise" the simon-pure Senator Loganberry. As his instrument, Jim selects Marina Von Minden, beautiful Viennese refugee. But matters become complicated when Jim falls for Marina... and she takes a liking for the Senator.
