In the heart of the Black Périgord, one of the most beautiful places in France, serious passions are boiling. The large and friendly Casal family is going through serious trials. Victor Casal's wife suddenly leaves for his younger brother Nils, whom everyone considers a failure. Victor almost goes crazy with grief, because he is losing his son, little Tom. Victor is supported by all his relatives: his elder brother Maxim, the same as himself, the owner of a notary office in Sarlat, Martial, the head of the family, who in his youth left his wife and children for the sake of fatal love, and Blanche, a tender, caring mother, the very embodiment devotion, which, oddly enough, found the strength to raise Nils, who was the fruit of her husband’s side love. Going through a divorce, Victor, on the advice of his father, moves to Rock, an old family estate where he spent his childhood. But strange things happen there: the floorboards creak alarmingly at night, invisible shadows knock on the windows, lights suddenly come on where they shouldn’t be lit, doors slam noisily... Victor retrieves the cut-up photographs from their hiding places, and then he comes across one covered with one in a word notebook. What tragedies took place within these walls? What terrible truth is about to come out?
