The "Castle in Flanders" of the title is where six aristocratic British officers are billeted during WWI. To pass the time, they play a scratchy old record on a ramshackle gramophone, eventually falling in love with the female voice heard on the recording. Meanwhile, the selfsame girl, a Parisian revue artiste named Gloria Delamare (Marta Eggarth) must fend off the attentions of her many ardent suitors. When she finally falls in love, it is of course with one of those six British officers, a man who has gone broke and is now a "suitable" beau for the low-born Gloria. The lucky swain is played by Paul Hartmann, one of Germany's most popular leading men of the 1930s. ~ Hal Erickson, Rovi
