Fabuła
You are a paranormal investigator who gets possessed by the demons you swore to protect people from. Now you have to survive for 7 nights and get through a series of rooms that will take you to a journey in your own mind and memories. You'll have to stop demons from getting close to you and solve every puzzle in your way in order to stay sane. All this leads to your primary goal: you are called to open The Secret Door. It's the only way to get out of this. Good luck.
