In director William Friedkin's supercharged thriller, William L. Petersen plays a "hot dog" special agent of the Secret Service who's out to arrest and convict an arrogant counterfeiter (William Dafoe) who has eluded the law for years and who flaunts his success. Dafoe has been asking for a down payment on a sale of bogus bills, but the amount is larger than the secret can authorize Petersen, undercover, to pay to entrap Dafoe in a "sting" operation. Petersen is forced to set up a dangerous plan to steal the advance money from another crook (John Turturro) and use it to buy bogus bills and bust the counterfeiter.As the film winds to its dark and exciting resolution, the distinction between the pursuing law enforcers and the pursued criminals will continue to blur.
