Sean Connery plays one of his early roughneck types in the British gangster picture Frightened City. The story takes place in a rundown section of London, where the citizens are held in the grip of extortionists. After several months of gang warfare, the six major "protection" rings agree to bury the hatchet and combine their efforts under the leadership of a mob boss (Herbert Lom). One of the gangsters opposes the mobster's rule, and is promptly rubbed out. Paddy Damion (Sean Connery), the dead man's best friend, swears revenge. After a bloody confrontation, Damion agrees to provide information to the police -- after plea-bargaining himself into a light sentence.
