Production has begun on the eleventh instalment in the Trial & Retribution series.

Called Closure, the new story guest stars Michael Brandon (Dempsey & Makepeace) as criminal profiler Max Stanford, alongside the regular team including David Hayman, Victoria Smurfit and Dorian Lough.

Closure joins Detective Chief Inspector Roisin Connor (Smurfit) two months into a murder investigation. A pretty, teenage schoolgirl, has been raped and murdered. The case is at a dead end and there is no witness, no weapon, no DNA.

Connor turns for assistance to a visiting American profiler, Max Stanford (Brandon), who is handsome, charming and highly respected in his field. After looking at all the case files, his view is that Connor is hunting a serial killer who will certainly kill again.

Of the new film, writer/ep Lynda La Plante said: “Any police officer will tell you there are cases that get right under their skin. Dealing with the murders of young, gifted, innocent teenage girls is tough even for the most experienced professional.”

The ninth story, The Lovers, peaked at 9 million viewers last year. Trial & Retribution X: Sins of the Father has already been filmed and will air on ITV1 later this year.
