Roger Lococco in effect signs his own death warrant by testifying to a Senate committee about a cabal within the U.S. intelligence community, but to back him up he needs Vinnie to testify as an O.C.B. operative — testimony that would end Vinnie’s career as an undercover agent.

Vinnie is called to Washington to investigate a counterfeiting operation designed to sabotage the Japanese economy. Frank warns Vinnie to be careful, that there is some kind of power play going on, because Paul was mysteriously sent to Thailand, leaving Mark in charge. Vinnie suspects Masters wants to set him up for throwing the coup of Isle Pavot. Mark is relieved of duty when he loses control after his former mentor is murdered. Vinnie meets Kate Gallagher.

Vinnie and Dan find evidence of the counterfeiting ring in Utah, but it seems to have come too easily, so Vinnie heads into the mountains to meet a billionaire recluse, Prescott Wilson, who might hold the key to the truth in the case. Frank and Vinnie convince Senator Pickering to delay passage of Senator Getzloff's trade bill while they search for the plane carrying the yen. Masters presents the Attorney General with photos of Vinnie and Kate talking with Wilson, as well as the printing plate with Vinnie's prints on it. Frank is ordered to arrest Vinnie.
