As Europe braces for war, a British socialite in a fictional country heads home on a train to be married. After receiving an untimely blow to the head, she's befriended and looked after by a fellow traveler — an older fellow citizen who is also traveling alone. When she awakens from a brief nap, her companion is gone (!!) and the other passengers deny having ever seen her.
A Hitchcock film that shares several elements and actors with 1940's Carol Reed-directed
Night Train to Munich.
