In 1944 Al Capone, the most notorious Mob boss in history, has already been released from prison. Though Capone is no longer the enormously powerful force who dominated Chicago’s underworld for years, he is still a thorn in the side of J. Edgar Hoover. The FBI chief knows that if he can somehow manage to get Capone to reveal details of crimes he and his Outfit committed, the Bureau has a good chance of nailing key members who now are active in the wartime black market. FBI agent Peter Vasco is perfect for the job. He has an in — his father once drove a truck for the Outfit — and his pre-FBI education gives him even better cover. His orders: pose as the priest he wanted to be before he dropped out of seminary, get close to Capone, and get Hoover the information he demands.
