A romantic retreat to an isolated house in the countryside turns tragic for two former stepsiblings turned lovers. Marc (Vincent Martinez) and Leá (Melanie Thierry) grew up together under one roof. As adults they share the same living conditions, but as lovers rather than siblings. Their relationship defined by passionate cruelty, they shut themselves away from the world as they drift into a heighted state of emotion. When a violent windstorm blows in and a nosy boss shows up, madness takes hold and a sacrifice is made. But when murder is committed out of love, can it really be considered a crime?
