The Third Man

Opportunistic racketeering thrives in a damaged and impoverished Allied-occupied Vienna, which is divided into four sectors, each controlled by one of the occupying forces: American, British, French, and Soviet. These powers share the duties of law enforcement in the city. American pulp Western writer Holly Martins (Joseph Cotten) comes to the city seeking his childhood friend, Harry Lime, who has offered him a job. Upon arrival he discovers that Lime was killed just hours earlier by a speeding truck while crossing the street. Martins attends Lime's funeral, where he meets two British Army Police: Sergeant Paine (Bernard Lee), a fan of Martins' pulp novels; and his superior, Major Calloway (Trevor Howard), who says Lime was a criminal and suggests Martins leave town.
