Set just before the start of World War II, Night Train to Munich tells the story of an inventor and his daughter who are kidnapped by the Gestapo after the Nazis march into Prague. A British secret service agent follows them, disguised as a senior German army officer pretending to woo the daughter over to the Nazi cause.
This was the second appearance by the characters Charters and Caldicott (played by Basil Radford and Naunton Wayne), all in movies written by Sidney Gilliat and Frank Launder. They also appeared in Crook’s Tour (1941), and Millions Like Us (1943). Their first appearance was in a movie much higher up the list in the Internet Archive Top 100.
