Undercover cop Mike Russell had a stroke of good luck when he saved a man from an attack by two street thugs. The man he saved turned out to be Andy Gerardo, one of the ranking captains of the Genovese crime family. Using his cover story --- an ex-cop fired for excessive force --- and street skills, Russell assimilated into the Genovese crime family in New Jersey and ultimately orchestrated one of the biggest Mafia takedowns of all time, leading to more than fifty arrests of mobsters, corrupt prison officials, and even a state senator.
