Doomsday Mom: The Lori Vallow Story is based on the true story of Lori Vallow (Lauren Lee Smith), who gained national attention when her children, JJ and Tylee, were reported missing from their Idaho home in the Fall of 2019. As investigators learned of Lori and her husband Chad Daybell’s (Marc Blucas) involvement in a doomsday-prepper group, a trail of mystery was revealed spanning five states and numerous questionable deaths, before the bodies of JJ and Tylee were found in the backyard of Chad’s home in June 2020. Linda Purl and Patrick Duffy also star.
