They find supplies for a flashlight and experience jump scares. It’s late in the evening on a dark, quiet forest road. A man travels home after work and suddenly has an accident due to a strange creature’s sudden appearance on the road. His car is irreparably wrecked, so he seeks help and finds his way straight into the house. Strange events begin to unfold there, and he explores the mysteries of the scary house from which he can find no way back.
