A family of five are found dead in a remote Essex farmhouse. Police initially suspect a murder-suicide, until the surviving son's behaviour starts to raise eyebrows.

On 7th August 1985, local police entered a secluded Essex farmhouse to find five dead bodies - young mother Sheila Caffell, her twin sons, and her parents. They'd been shot and killed. Initially it appeared to be the scene of a tragic murder-suicide committed by the troubled mother, Sheila. But fresh evidence would emerge to put Sheila's brother Jeremy Bamber firmly in the frame. Arrested, charged, and convicted of all five murders, he was sent to prison for life. However, for the last 35 years, Bamber has been fighting his conviction from his maximum-security prison cell, consistently maintaining his innocence. With access to previously unheard audio tapes of Jeremy Bamber, this four-part series will use first-hand testimony and unseen archive footage to explore evidence that has emerged since the original trial and to re-examine the shocking events at White House Farm.
