Serpico movie

Frank Serpico is a young, inexperienced cop who starts out on patrol. Later, he starts to work as an undercover cop who busts all sorts of criminals, but mostly drug dealers and pushers. Since Serpico is a young man living in the 70s, he lives as one. His image, based on how others look on him, shows him as just a hippie and the criminals he busts have no idea he is really an undercover officer. Everything is working out well, except the money situation. Serpico refuses to accept money, as the other officers do. He feels this isnt right, and wants to expose the situation. Who he thought were his friends now turn into his enemies when Serpico takes the stand on a grand jury investigation. He continues to work undercover, and his life is placed into jeopardy at the hands of his colleagues.
