Frenchman Andr é (Michael Galabrou Michel Galabru) and her granddaughter Jeanne (Julie Drumm Julie Delarme), whose quiet life was broken by the arrival of World War II and the German occupation of France, find it even more unacceptable that a room in their home was requisitioned as the living room of a German officer Werner (Thomas Juat Thomas Jouannet). They remained indifferent to the enemy officer, especially Jeanne, who never spoke to the officer, even when he said hello to them. Unexpectedly, after spending many days together, the young officer talked with them about his life, music and French culture, revealing his secret inner world under his Nazi uniform. At the same time, Jeanne is also actively involved in the organization of underground resistance against the German army in France. Gradually, a strange emotion developed between two young men and women from opposing sides. When they parted, this emotion turned into a sentence in Jeanne's mouth, the first thing she said to him.
