Hundred year anniversary of the Belgian revolution (which resulted in the independence of Belgium in 1830).

Espionage movie about a German-Belgian family in occupied Brussels, and besides, an ode to the heroîsm of the Belgian soldier.

Kaatje, the daughter of the miller Schoonejans, and Jef, a little shepherd, who live near Delft, are happy together. In a floral parade, the carriage the two children have decorated with tulips wins the first prize. The next day, during a thunderstorm, lightning destroys the mill and kills Schoonejans. A life of misery starts for his widow and daughter. Remembering how the theatre manager Boolmans had applauded the dancing of Kaatje and Jef at the floral parade, the widow takes her daughter to Amsterdam, where Boolmans engages Kaatje. The years pass, and Kate has become a famous dancer.

The red night was set within the space of a few hours and in two locations - the rich madam Lesparre's old castle (where celebrations are underway to mark the marriage of her daughter Ginette to the handsome Robert) and the sinister mill 'Moulin-Maudit'. The young couple leave to their honeymoon driven by a mysterious chauffeur. Following a breakdown in open country they are forced to seek refuge in the mill, where untold horrors wait: blood oozing from the ceiling, a body wrapped in a tarpaulin, a menacing dumb figure and an old woman, etc.
