This was Alfred Hitchcock’s last movie filmed in England before leaving for Hollywood. The plot involves a train somewhere in central Europe with some British citizens on their way back home. An old English lady named Miss Froy is involved in some kind of espionage. She befriends a young woman named Iris Henderson who is going home to marry a rich man she doesn’t love. When Miss Froy disappears from the train and all the other passengers and crew swear she was never there Iris recruits Gilbert Redman to help her solve the mystery. There are comic touches that involve a pair of friends named Caldicott and Charters who are obsessed with reaching England in time to watch the National Cricket match. In fact, the comic bit they did in this film was so popular that the actors, Naunton Wayne and Basil Radford respectively, reprised their characters in a number of films for many years afterward.
Hitchcock builds up the characters with plenty of background and personal details in scenes that take place before the train ride and once the young couple begin delving into the mystery it is obvious that a criminal conspiracy is taking place to kidnap Miss Froy, although no apparent reason exists. On the train is a noted brain surgeon and he tries to convince Iris that a serious blow to the head that she sustained just before getting on the train is the source of her delusion about the missing Miss Froy. Later on, we find out that he is the ringleader of the plot.
Finally, Miss Froy is freed and she reveals to Iris and Gilbert that she is a British spy and she must flee the train and go cross country to return to England. But first she teaches Gilbert a musical phrase that is code for some top-secret information. The adventure comes to a climax in a gun battle between the storm trooper and the English passengers as they attempt to take control of the train and flee over a border to a non-hostile country. After several casualties they escape and return to safety. When they reach England, Iris decides to forsake her rich loveless bridegroom and go off with Gilbert. But first they head for the British foreign office to give them the musical code message. But just as they reach the office Gilbert realizes he has forgotten the music. But then hears the tune being played on a piano in the room they are about to enter and they see Miss Froy playing the tune.
This all sounds like a ridiculous jumble and in a way it is. There are all kinds of odd things going on as there always are in a Hitchcock film. A homicidal magician complete with a booth for making women disappear. A mysterious burn victim with bandages that cover her face who is brought on the train well after Miss Froy disappeared. There’s a deaf-mute nun in high heels. A platoon of storm troopers that I guess are supposed to be German. An avalanche, a murdered singer, clog dancers, a comedic Italian innkeeper who promises things he can’t deliver in four or five languages and scantily clad women.
But it’s actually highly entertaining. All the little details of the story are well done and diverting. The various characters are given enough development and even the villains are well rounded characters. I thoroughly enjoy this movie and highly recommend it.
