When a deported gangster dies in Italy, the U.S. Treasury Department is very interested in the one million dollars Madigan owed the government, but managed to take to Italy with him. They send Agent Jason Phister over to Italy to nose out the million. His criteria for the job is that no one would ever guess he's an agent of the United States government.
