The Bamber family, with the exception of son Jeremy, are found dead at White House Farm. But the case might not be as open-and-shut as first thought.

DC Stan Jones and his number two Mick Clark speak to Jeremy and relatives of the murdered family, but their picture of what really happened that night at White House Farm remains inconclusive.

After a vital discovery at the farm, Stan and Mick feel closer to shoring up their own suspicions about Jeremy. The arrival of Brett, a friend from New Zealand, increases tensions between Jeremy and Julie, while Ann grows ever more alarmed and suspicious of her cousin Jeremy's behaviour, and his handling of the family estate.

The funerals approach, and without the answers he needs and still more questions being thrown up from White House Farm, Stan's efforts remain fruitless. When all looks lost for Stan and Mick solving the case, a vital witness comes forward.

Even though the testimony of a vital witness fills in the blanks and answers some of Stan and Mick's questions, even more complications are thrown up. This aside, Stan and Mick are still able to make the first arrests of the case and continue questioning in the hopes that they lead to further solutions.

As the case races towards its conclusion and all evidence and information is gathered, scrutinised and interrogated, a very publicised and polarised trial begins, calling those involved in the case to testify before the jury and packed gallery.
