Contraband 1940 is a wartime spy film by the British directorwriter team of Michael Powell and Emeric Pressburger, which reunited stars Conrad Veidt and Valerie Hobson after their earlier appearance in The Spy in Black the previous year. On this occasion, Veidt plays a hero, something he did not do very often, and there is also an early uncredited performance by Leo Genn.
It is November 1939 the Phoney Warstage of the World War II. Denmark is still neutral, but Danish Captain Andersen Conrad Veidt and his freighter Helvig are stopped in the English Channel by Lt. Commanders Ashton Joss Ambler and Ellis Harold Warrender for a cargo inspection in a British Contraband Control Port.He receives two shore passes for himself and his First Officer Axel Skold Hay Petrie to dine with Ashton and Ellis, but the passes and Helvig s motorboat are stolen by passengers Mrs. Sorensen Valerie Hobson and talent scout Mr. Pidgeon Esmond Knight. From a cutout newspaper train schedule, Andersen is able to figure out they are taking a train to London and catches up with them but, when the train arrives in the blackedout metropolis, he is only able to hold on to Sorensen. ........
