This Fritz Lang film reminded me some of Hitchcock, then on the analysis bit on the Criterion disc the guy spent considerable time comparing Lang to Hitch. So, I must have been on the right track there.
Ray Milland gets out of an asylum, and just wants to go to London, even though it's being bombed. While waiting for the train he attends a carnival type event sponsored by the "Mothers of Free Nations." He ends up winning a cake and on the train someone attacks him and steals his cake. This, of course, leads him into running for his life from a Nazi spy ring and from the police.
A good show, even though sometimes Milland did things that make you want to shout at the screen.
