Producer, writer and director Eli Roth hosts this new paranormal anthology series, which presents stories of hauntings that have had a devastating effect upon the lives of the people who have experienced them. The series draws upon both eyewitness accounts, as well as reconstructions and re-enactments that play out like mini-horror films. In the series premiere, "Portal to Hell," when a single mother and her young son rent an old house in the country, they discover the place is filled with ghosts - and not all of them are friendly.
