Nazi Germany occupied the Grand Duchy of Luxembourg from 1940 to 1944, with the intention of returning the Luxembourgers to their so-called German roots. Paradoxically, this attempt to incorporate Luxembourg into the Third Reich triggered the nation's self-awareness. Using mostly unseen archive footage, the film tells the story of the clash between ideologies: the Nazi vision of a 'German' Luxembourg, colliding violently with the idea of an independent Grand Duchy. For a people who where becoming aware of their national identity, this was a huge cultural shock. The emotional backbone of the film rests on the many testimonies of the people who lived through that tragic period.
