You’re home alone with your two little sisters, Yumi (older) and Mio (younger), while your parents are away for the weekend. You’re exhausted and taking a nap in your room. The girls are happily playing together in the living room. Then… a knock comes at the front door. Since you’re sleeping, the two sisters go to check who it is. Through the door they hear a voice that sounds exactly like your mom — but something is horribly wrong. The voice is distorted, unnatural, and keeps repeating things your mom would say in a creepy, off-tone way. It’s a skinwalker trying to trick them into opening the door.
