Purgatory. A horrible place that stands between the mute young man and the afterlife. Attempts to escape the place have proven futile time and time again for Isaac and others in this wretched place. An endless basement with the lost souls of deceased children. One such child is Samson, who arrives in the place with rage in his heart and tears streaming down his face. Now he too must face the demons of this place to enter Heaven. Can he surpass the unholy beings of this place to earn Isaac and his other allies passage into the Golden Gates of Heaven, or will he be stuck in a loop of death and suffering until he descends into Hell? This is the story of Isaac, and the Binding of Souls.
