It is summer 1989 and fifteen-year-old Clotilde is on holiday with her parents in Corsica. On a twisty mountain road, their car comes off at a curve and plunges into a ravine. Only Clotilde survives. Twenty-seven years later, she returns to Corsica with her husband and their sulky teenage daughter. Clotilde wants the trip to do two things to help exorcise her past and to build a bridge between her and her daughter. But in the very place where she spent that summer all those years ago, she receives a letter. From her mother. As if she were still alive.
