Léa (Elsa Zylberstein) and Juliette (Kristin Scott Thomas) are sisters. Juliette has just been released from prison after serving a long sentence. Léa was still a teenager when Juliette, a doctor, was convicted of the murder of her six-year-old son. Life together isn’t easy to begin with. Juliette has to relearn certain basics. The world has moved on and she often seems confused. Although she may seem cold and distant, her attitude stems more from her being ill at ease. Helped by some, such as the kindly but tactless social worker and her open-hearted but depressed parole officer (Frédéric Pierrot) whose confidante she becomes, Juliette is also rejected by others, particularly employers who throw her out as soon as they find out what she did. But a huge questions hangs over Juliette's renaissance. Why did she do such a terrible thing fifteen years ago? For all the others, it's a recurrent thought that they dare not put into words. And for Juliette, locked away in her secret, it's a burden to bear, which holds her back from engaging in her life and believing that she too has the right to be happy.
