Paranormal State (2007)

S5E3 Spirits of the Slave Dungeon

Ryan arranges a two-night investigation at a genuinely haunted jail in Charleston, SC, but the PRS team soon discovers that the spirits trapped there are enduring a form of torment. During a ghost tour, they sense that something is profoundly off. It's clear that the true victims aren’t the paying guests but rather the spirits themselves, who are suffering from historical injustices. PRS is determined to uncover a way to bring healing to the lingering pain and social injustices experienced by the spirits of former slaves.
