'A householder who is clearing out the loft comes across a carefully concealed box containing a video camera.
'When he plugs it in, unsure due to its age that it will even play, what he sees there has him immediately calling the police.
'Senior Sergeant Veronika Pope and her team in the Special Crime Squad study the footage of the torture of four individuals held captive, all physically and mentally abused.
'Assured this is no hoax, although all indications are that this happened long in the past, the team races to trace the identity of the victims.
'Someone got away with murder once, will Sergeant Pope permit them to do so again?'
