In an elegant spa town on the Franco-German border, the slow summer days pass seamlessly in 1914: Nobody wants to believe what is brewing over Europe, including the siblings Franz, Luise and Victoria Leiling, who call themselves “the three musketeers”. But while the piano music floats out of the windows of the assembly rooms and the parrots in the aviaries spread their beautiful wings, in the streets young men cheer on the start of the First World War, certain that they will be victorious. For Franz, Luise and Victoria nothing will be the same after this 1st August.
