Nick Groff, a paranormal investigator who's "on a mission to discover something new in the paranormal field", and his paranormal researcher Katrina Weidman spend 72 hours together locked down in the most haunted locations in their quest to learn more about the unknown. They stay with the dead at these reportedly haunted places, many of which have never been filmed for a production and some will be investigated for the first time on television. 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".
