This is a French-Canadian drama. The plot summary makes it sound like a soap opera.
Diane Messier lives on a farm in the Eastern Townships, near the American border, with her daughter Sarah and her two sisters, Carmen and Julie. Following a tragic accident, Diane feels constantly threatened and even believes her house is haunted. Worried by her daughter’s actions, Angèle returns from Florida to bring comfort to Diane and try to reunite the family clan.
