Plot
On a dark and rainy night, a woman (Lotta Losten) comes out of a room and turns off the hallway light, which causes a long-haired, humanlike silhouette to become visible at the other end of the hallway. Surprised, the woman turns the light back on and the silhouette vanishes. Switching the light off and on, she watches the silhouette appear and disappear, stopping when the silhouette suddenly moves so close it is inches away from her face. Gasping, she turns the light back on and tapes the switch in that position to prevent the silhouette from returning.
The woman goes to bed, leaving the lamp on her bedside table on and the door leading to the lit hallway ajar. She hears creaking sounds and looks towards the doorway. The hallway light starts flickering and eventually turns off. Scared, she hears footsteps approaching the bedroom and hides under the blanket. After a few seconds of silence, she peeks out. The door opens wider by itself, which terrifies the woman.
The lamp flickers. From under the blanket, the woman looks towards the power strip it is plugged in to. She nervously reaches out, locates the plug, and pushes it in more firmly. The flickering stops. The hallway light clicks back on and she sees it is on again and the door is only slightly ajar again. She is relieved, but unfortunately suddenly sees a monstrous humanoid with all-white eyes and an open mouth at her bedside table. The monster turns off the lamp, and the screen goes dark.
