When John Colton is promoted and ordered back to Washington, General Wheeler takes his place with orders to break up a nation-wide counterfeiting gang that is based in New Orleans. Yancy objects to the general's tactics of raiding every gambling house in the Crescent City and impounding their patrons' money until it can be combed for bogus bills and is thrown in jail. Even locked in a cell Derringer manages to learn that the source of the phony currency is a criminal gang masquerading as army officers.
