The final chapter of this Hellraiser anthology arrives with perhaps its most shocking stories, as Christopher Sebela (Dead Letters) teams up with Matt Battaglia for a tale of a hoarder unlike any you’ve seen on reality TV. Also, Ben Meares and Peter Bergting (Baltimore) show us a scientist racing to crack the secrets of the puzzle box, and in the finale of “The Hunted,” Pinhead comes face to face with those who want to steal his pins.
