Paranormal Lockdown

Paranormal Lockdown is a paranormal reality television series that was executively produced by Nick Groff, formerly of Ghost Adventures. The series follows Nick Groff and fellow paranormal researcher Katrina Weidman (formerly of Paranormal State) as they confine themselves for 72 straight hours in what they claim to be some of the most haunted locations.

The first season aired on Destination America from March 4, 2016 to April 8, 2016. The second season aired from December 16, 2016 to March 3, 2017 on TLC. On November 20, 2018, it was announced that season three would premiere on December 4, 2018, returning to Destination America. On February 14, 2019, Groff announced via a video Instagram post that Paranormal Lockdown would not be returning.

Premise
The series features Nick Groff, a paranormal investigator who is "on a mission to discover something new in the paranormal field", and paranormal researcher Katrina Weidman who both spend 72 hours together in reportedly haunted places. 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". The opening introduction for the show is: 72 hour confinement...in the most haunted locations...in search of groundbreaking evidence.

Reception
Investigator Ben Radford states that the claims of living 72 hours in a haunted house as some sort of a challenge is "absurd." People all over the world claim to live in haunted locations, apparently longer than 72 hours. Before you can claim you are living in a haunted house, "ghosts must be proven to exist", a claim that the paranormal community has yet to prove. There are many methodological problems with their investigative techniques, according to Radford. "They fail to properly investigate and verify their assumptions at virtually every step, making leaps of logic and guessing far beyond the evidence". Lockdowns like what you see on this reality show are using ineffective techniques with equipment not meant to be used for this purpose, to look for something that has not been proven to exist or even defined. "A stakeout (such as these) is essentially a scientific experiment without the science". Completely lacking in controls. "Groff and Weidman... are walking around a house with a camera crew, literally and figuratively in the dark. The only things they're testing are their video editors' endurance and the patience of their viewers. These 'reality' television shows are entertainment, not investigation."
