Many spiritualists believe that some locations have an unusually high concentration of psychic energy. Beneath the ground we walk on, invisible routes may be infused with the spirits of those who came before us‚ and some routes are still traveled by spirits that have not passed on.On the surface, Edd and Beth's three-bedroom ranch house seems like the perfect place to raise their toddler‚ but a few weeks after they move in, they discover that they are not alone.
