He strolls on in thinking he just caught a lucky break and for a while, it would appear as though he did. But soon enough, he realizes that the house won't let him leave, as its doors are all locked while its windows cannot be opened or broken. Destiny has brought Thomas to this place. What does it want from him? Will he survive the ordeal?
