The stories of individuals who do the unthinkable and kill those closest to them - family killers. Starting with Michell Quy, a newly married man who, when his wife goes missing, spins a web of lies in the media to deflect the police from the grisly truth. Jeremy Bamber, the unlikely killer who murdered three generations of his family. And finally, Stuart Hazel, convicted of abusing and killing his partner's granddaughter and hiding her body in their attic.
