Anne has a very active imagination, only natural for a writer. But in her mid-30s, she still knows practically nothing of her own family's past. After her mother's death, Anne discovers old photos and letters that convince her to take a closer look at the life of her parents, Michael and Léna. The young couple met in the concentration camps during World War II, later moving to France to start their new life together.

Soon, Anne's research into their Jewish history and ties to Lyon's communist party reveals the existence of a mysterious uncle, Jean, whom everyone seems intent on forgetting entirely. As she gradually closes in on the discovery she didn't know she was looking for, her father grows ever more ill, and may take the secret that kept them apart for so long to his grave.

In a journey that stretches from post-war France to the 1980s, Anne's destiny intertwines with her father's past until they form a single, unforgettable story. This French film is unrated and 110 minutes long.
