Debbie lives in terror in her Kentucky home following an encounter with a half-human figure bearing rams' horns. When PRS learns the same figure appeared before Debbie's sister, Donna, just before she took her own life, it's only the beginning. A psychic hunch leads PRS on a week-long interstate odyssey with a shocking demonic twist involving a former client.

PRS and psychic/medium Chip Coffey travel to famously-haunted Gettysburg, Pennsylvania to investigate shadows, loud footsteps and an unexplained boom that has guests fleeing the hotel and pushed the owners to the end of their rope.
