The director collects postcard of the republican Spanish refugees' arrival in France in 1939. His attention was first attracted by on of these cards mentioning a "concentration camp", a term which, even if it doesn't means by itself extermination, was already used in nazi Germany. The film relates both his search for the postcards and the story of these Spanish refugees, some of whom were later sent in the nazi camps. The way the story is told may seem a bit selfish, but it opens a reflexion on memory and forgetting. how could postcard be made of this event? how could everyone forget it 75 years later? No answers, just unsettling questions...
