Serpico
Serpico is a 1973 American crime film directed by Sidney Lumet and starring Al Pacino. Waldo Salt and Norman Wexler wrote the screenplay, adapting Peter Maas' biography of NYPD officer Frank Serpico, who went undercover to expose corruption in the force. Both Maas's book and the film cover 12 years—1960 to June 15, 1972—in the life of Serpico, who was trying to be an honest policeman.The above text is a snippet from Wikipedia: Serpico
