Retired NYPD homicide detective Steve DiSchiavi and physical medium Amy Allan investigate disturbing reports of vicious paranormal activity at an ailing U.S. Air Force veteran's home in Abilene, TX.
Their client and father of four, Sean, has braved many dangers in his life when he served multiple tours of duty for the U.S. Air Force in Iraq and Afghanistan. However, he claims no firefight compares to the horrendously debilitating paranormal activity he's experiencing inside his own home. For years, he and his courageous family have withstood the attacks, refusing to move, but recent clashes have them on the brink of collapse. Now, Sean's health is in rapid decline and fears the house will eventually destroy him.
During their separate vexing investigations, Steve unearths the property's dreadful history as a bloody Native American warzone over the span of nearly a century; when the tribes were then exiled from their land, a Kentuckian named John Hunter Herndon sought to profit from the property by exploiting hundreds of slaves to grueling working conditions. Herndon would eventually lose his fortune by betting on the Confederacy. Since then, each subsequent landowner has been the victim of ghastly tragedy. During her intense nighttime walk, Amy confronts a lethal shadow creature known simply as "The Dark One" and a horde of dead she refers to as "the damned", who encircle and suck the life from the living.
In the episode's stunning conclusion, Steve and Amy come together for the first time to reveal their results to their clients - and each other. Steve reveals the brutal history of violence between warring Native Americans factions and the unfortunate circumstances surrounding the properties' original settlers. Amy then vividly explains her disturbing encounters in the home, and recommends Sean take extreme action before the attacks continue to ruin he and his family.
