Set in both 1973 and the early 2000s, Steeltown Murders centres on the hunt to catch the killer of three young women in the Port Talbot area and the remarkable story of how - in the first case of its kind - the mystery was solved almost 30 years later using pioneering DNA evidence.
Contrasting the policing methods of the 1970s with the forensic breakthroughs of the early Noughties, Steeltown Murders is a portrait of a town dealing with the repercussions of an unsolved case three decades on, and asks if justice can ever truly be found.
Philip Glenister (Life On Mars, State Of Play) and Steffan Rhodri (In My Skin, Gavin & Stacey) lead the cast as DCI Paul Bethell and Phil ‘Bach’ Rees, with their younger selves played by Scott Arthur (Good Omens, Borg McEnroe) and Siôn Alun Davies (The Sandman, Hidden) respectively.
They will be joined by Keith Allen (The Pembrokeshire Murders, Marcella), Priyanga Burford (Industry, No Time To Die), Sharon Morgan (Yr Amgueddfa, Gangs Of London), Nia Roberts (Red Rose, Yr Amgueddfa), Elinor Crawley (Vikings, Ordinary Lies), Gareth John Bale (35 Awr, Y Pris), Kriss Dosanjh (The Larkins, Casualty), Matthew Gravelle (Silent Witness, Broadchurch), Amy Morgan (Mr Selfridge, Showtrial), Dyfan Dwyfor (A Very English Scandal, Bang), and more.
The four-part series begins Monday 15th May on BBC One.
