Zak, Nick and Aaron head to Natchitoches, LA, to investigate the Magnolia Plantation. Many slaves labored and died at this cotton plantation, which was built in 1830. The crew looks for evidence of voodoo rituals slaves may have used to seek revenge on the owners.

The team goes to Philadelphia to investigate the abandoned Eastern State Penitentiary. Driven insane by solitary confinement, torture and disease, the inmates suffered an ugly and violent existence. Their angry spirits continue to roam the corridors.
