Top FBI agent Buddy looks exactly like Barton, the deceased patriarch of the Logut mafia family. He goes undercover as Barton to expose the family’s arms smuggling. Inside, he survives power grabs from Luca, probes from Barton’s stepmother Susanna, and uses their shared crescent birthmark to avoid exposure. He falls for Barton’s wife Elise, wins over bodyguard Haruko, and secures the San Francisco docks. With evidence in hand, he and FBI Deputy Director Helena plan a final raid—but FBI Director Burke is the mafia’s deepest mole. He and the Raine family spring a trap; Helena is shot. In the battle, Buddy kills Burke and Carlos. Dying, Burke reveals Buddy and Barton are twin brothers—stolen as infants and groomed to be a mafia mole inside the FBI. Torn between two bloodlines, Buddy stands with Elise, Susanna, and Haruko—as Helena, presumed dead, twitches her fingers. Cliffhanger.
