A small town in Brittany, by the water. A close-knit community where everyone knows each other. A woman, a lawyer, mother of three children and on maternity leave, sees her daily life shattered when her husband disappears overnight, without explanation.
Where is he? What has happened to him?
Accused of being responsible for his disappearance - or even his eventual death - she will investigate, and struggle, alone, to try to understand what happened, and above all who the man she loved really was. Because, if she trusted him blindly, he was obviously far from being who he claimed to be.
Will she make the right choices? Will she surround herself with the right people? What is about to fall on her shoulders is far from what she could have imagined...
