This supremely entertaining and suspenseful World War II spy thriller features Joel McCrea as a European foreign correspondent and Laraine Day as his love interest. After a diplomat in London is kidnapped, McCrea searches for Nazi spies in London and Holland with help from reporters George Sanders and Robert Benchley. Nothing is what it seems as plot twists abound, and Westminster Cathedral and a giant windmill provide settings for two of the many classic Hitchcock showpieces that appear in the film. The film's propagandistic ending, which pleas for support for the war against Nazi Germany, is fascinating when viewed from a historical perspective.
