When one man goes against the mob, he starts a war that blows the city apart...

London, 1961. It's a city where gangs control the streets and extortion thugs call the shots until a ruthless accountant organizes the major racketeers into one ruling syndicate. But when the crime ring double-crosses mob enforcer Paddy Damion (Sean Connery), the fuse is lit on a brutal war that explodes in every pub, club and street corner of the West End. Now Paddy is trapped between the strong-arm of the mob and the long arm of the law, a hunted man alone in The Frightened City.
