Code of Silence is a 1985 American action film directed by Andrew Davis, and starring Chuck Norris and Henry Silva. It was typical for the genre and the star but filmed on location in Chicago with a few sub-plots. It featured Norris as Sgt. Eddie Cusack, a streetwise plainclothes officer who takes down a crime czar / drug lord responsible for officers being wounded in a botched drug raid. In the film's climax Norris teams with a more than menacing crime-fighting robot named "Prowler".
