A man in London tries to help a counterespionage agent. But when the agent is killed and the man stands accused, he must go on the run to both save himself and also stop a spy ring which is trying to steal top secret information. (IMDb)
It’s bookended by a slow beginning (Miss Smith is annoyingly cryptic) and an abrupt, too-easy ending (Hannay figures things out super quickly) but in between them is fun fugitive plot that constantly dishes out unexpected twists: Just when you think he’s getting away he gets caught; just when you think he’s done for he finds a new way out. Dashes of comedy (see the hilarious impromptu political speech scene; Hannay and Pamela’s handcuff experience) mix well with the film’s solid suspense.
