Differing from many documentaries about the crimes of serial killers, this film dives into the experience of a family who for decades lives unsuspectingly with one of the worst sociopaths in US History, as well as the angst and frustration of those who tried to identify who he was. A spouse, a son, in-laws, nieces, nephews, grandparents sit next to him as Holidays and years fly until the shock and outrage ensues after the day he is arrested and then eventually confesses. This account shows first-hand, the human side of the victims of mass killers, as well as the killer's family and how they try to comes to terms in their search to make sense of the unthinkable.
