The dark history of Spring House, a beautifully restored plantation mansion on the outskirts of New Orleans, has long been forgotten. But something sinister lurks beneath the soil of the old estate. After heiress and current owner Caitlin Chaisson is witness to her husband’s stunning betrayal at her birthday party, she tries to take her own life in the mansion’s cherished gazebo. Instead, the blood she spills awakens dark forces in the ground below. Chaos ensues and by morning her husband has vanished without a trace and his mistress has gone mad. Nova, daughter to Spring House’s groundskeeper, has always suspected that something malevolent haunts the old place, and in the aftermath of the birthday party she enlists Caitlin’s estranged best friend, Blake, to help her get to the bottom of it. The pair soon realizes that the vengeance enacted by this sinister and otherworldly force comes at a terrible price.
