He explains it is the furnace in the old house and insists that she does not check it out. Granny doesn’t suspect a thing, but she should. Her grandson has a secret. You are about to find out what that is when you find yourself locked up in the basement. You have one hour while he is out running errands for granny to escape before you become another secret lost in the basement......
