Still (2017)

In the dead of night, a loud thumping knock at the door freezes the bone to the marrow. Who could that be at this kind of hour? From inside the house, a young woman home alone who waits for her husband can only struggle to keep her mind from playing tricks on her. However, there must be someone out there in the dark and thick shadows. Who wants to do her any harm, and how can one escape when all the doors are locked?
