At night you hear a strange sound in the basement. After a long time of waking up and collecting your thoughts, you decide to check the source of the noise. Lighting the way with a phone torch and holding a taser in your hands (just in case), you open the door and descend into the darkness of the cold underground room.

At first, everything looks as usual - just a few things knocked on the floor and a small window to the outside open... but then somewhere behind the shelves and boxes comes a rustling sound.
