The Sweeney

Turkish policeman Captain Shebbeq arrives in England for his old friend Regan to help him track down a gold-smuggling ring, possibly connected to an insurance firm which is fire-bombed. Their joint investigation leads them to uncover another form of smuggling, in the process of which someone puts a bomb in Regan's car. However, he does have the last word on the zealous fellow cop who had him suspended.
