Storyline:When a young mother (Kathryn Hahn) is asked by her parents if their grandchildren can spend a week with them, Rebecca (Olivia DeJonge) and Tyler (Ed Oxenbould) happily begin the train ride to their grandparents' remote farm. Once there, the four spend a harmonious and fun day together. Only the strict specification of the grandfather (Peter McRobbie), the room after 21.30 clock not to leave, makes the two children a bit suspicious. But soon after they realize that the rule does not exist without reason. When the siblings hear strange noises at night and want to get to the bottom of their origins, they observe how their grandmother (Deanna Dunagan) behaves very strangely. Your grandfather does this the next day as a trifle. But even during the day, the two seniors behave increasingly sinister and threatening, so Rebecca and Tyler finally doubt whether they will ever return home.
