`Paranormal Lockdown' brings together seasoned ghost hunters Nick Groff and Katrina Weidman for round-the-clock, multiday investigations that have never been conducted before on a paranormal TV series. For 72 hours straight, the hosts live with the dead in some of America's most haunted places, from the creepy Trans-Allegheny Lunatic Asylum in West Virginia to the foreboding Franklin Castle in Cleveland. Groff and Weidman believe that the longer they stay, the more the spirits will communicate with them and the more information they can gather about the unknown.
