Steeltown Murders focuses on a groundbreaking criminal investigation from the turn of the millennium, where DNA evidence was used to finally solve a case that had gone cold decades earlier.


Philip Glenister (Belgravia) and Steffan Rhodri (Gavin & Stacey) lead the cast as detectives Paul Bethell and Phil 'Bach' Rees, while Gareth John Bale co-stars as their colleague Geraint Bale.

All three worked diligently to find justice for the families of three young women who were raped and murdered in the 1970s, casting a terrible shadow over the Neath Port Talbot county in Wales.

The dramatisation comes from writer Ed Whitmore, best known for ITV's Manhunt, while the four-part series is directed by Marc Evans (The Pembrokeshire Murders).

Steeltown Murders is based on a true story, unravelling the mystery of three murders that took place in Neath Port Talbot in 1973, which couldn't be solved contemporaneously.

However, decades later, following huge leaps forward in technology, three veteran detectives teamed up to finally seek justice for the victim's families using a then-groundbreaking technique known as familial DNA profiling.
