I can only remember these teenagers got into this mansion and they went into a closet and there was a fake skeleton and a oojuii board they played it and then they were all trapped in the house, one man tried to get out from the attic I think and there was this pretty chinese woman and she said to him the only way out is through here a tiny vent with tarantulas coming out of it, and then she turned into a spider and her teeth shot out into him and liquified his insides and left him a bag of skin on the floor, I also remember that it was someone's birthday party called billy. And there was a bald man who I think was the bad guy.
