In a town on the French Riviera, detective Yvonne (Adèle Haenel) is the widow of police chief Santi, a local hero idolized by their young son. When she realizes her husband was not the model of virtue she believed him to be and that an innocent man, Antoine, has spent eight years in prison as Santi’s scapegoat, her world is thrown into turmoil. Yvonne wants to do everything she can to help the young man get back to his life and his wife (Audrey Tautou). Everything, that is, except exposing the truth. But Antoine is having trouble adjusting to life after prison and soon blows a fuse, leading to a spectacular sequence of events.
