Passenger to London (1937)

A British agent is bring some retrieved government documents back from Paris but he is being hunted by enemy agents and is killed on the train to the coast. He manages to hide the plans in the luggage of fellow passenger Barbara Lane (Jenny Laird). Frank Drayton (John Warwick) is on a mission to retrieve the plans.

Frank hunts Barbara down to a cheap hotel owned by the ridiculously haughty Dorothy Dewhurst. Frank hits it off with Barbara though finds it difficult to find the plans. The enemy agents are meanwhile also closing in on Barbara and the plans...

A fun little quota quickie. The story is a little limited, some of the characters a bit one dimensional (especially the enemy agents Vautel (Paul Neville) and Veinberg (Ian Wilmot) who are almost self-parody) but Warwick and Laird work well together. The film is short and doesn't waste much time.
