The children were afraid of light and would become ill if exposed to light, so the curtains at home were drawn tightly all year round. In such a dark old house, Grace welcomed three new servants. After the arrival of these three people, Grace was chilled - the curtains were often opened, the door was opened for no reason, the piano sounded automatically, and her daughter said that she often saw strange men in the room. Grace fell into a state of mental tension. She didn't understand why strange things happened again and again, and why her husband didn't return. And she finally realized that all the fears actually came from herself, but things were irreversible...
