An old man reads the diary of a young Jewish girl written during the German Occupation 60 years earlier… Sarah Rosemblum was 25 at the time. She was young, beautiful, in love… He was called Hans, an SS officer repelled by Nazi ideology, one of those who despised their uniform and used their position to provide Jews with false identity papers. Renamed Louise Berger, Sarah lives under the protection of Huguette, a generous cabaret singer who hides Jews and helps them get across to England. In her house, sheltered from the rest of the world, this unlikely couple can give free rein to their love affair. Unwittingly, they awaken the jealousy of another resident in the house: Robert, a young 16-year-old who is madly in love with Louise. Passions rage under the sphinx-like eye of Margot, Huguette’s mother, who has not said a word since her son’s death. But war catches up with those who love each other… Soon they will have to flee, until escape is no longer possible. Who is this old man immersed in Sarah’s story?…
