Iona's body is transported on a sled in the blizzard before being buried. Increasingly disturbed by strange noises, anonymous calls and videos that show her with her husband in private, Nathalie walks the halls of the huge chalet in search of her daughter. She discovers her serenely seated facing the hearth and orders her to close doors and shutters, before rushing into her office where she barricades herself. While Alice, frightened by her mother's behavior, bangs desperately on the office door, Nathalie receives a new video whose content will prove to be premonitory.
