A magistrate is plunged into a murky world of crime in Mudtown, a "fast-paced, witty and gripping" Welsh crime drama. 

Erin Richards (Gotham) and Tom Cullen (Downton Abbey) will lead the cast, yet a host of Welsh talent will also star in a drama that has been filmed in Welsh and English. 

A co-commission between Welsh language free-to-air channel S4C and All3Media International, the Welsh-language version of the show — which comes with English subtitles — will be coming to the BBC iPlayer and S4C later this year. 

For those who'd rather wait for the English version, it will be debuting on UKTV's legal channel Alibi in the Spring of 2025. 

The thriller was written by Hannah Daniel (star of Keeping Faith, Holby City and Cleddau/The One That Got Away) and Georgia Lee, who also sits on the Bench as a Magistrate. 

"I'm thrilled that we get to bring Hannah and Georgia's razor-sharp scripts to life in a way that will make our audiences laugh, cry, gasp and stay on the edge of their seats," said Helen Parry, head of drama for UKTV. 

"The characters are colourful, the crimes are complex, the twists are non-stop, and the whole show is shot through with wit. This series will give our Alibi audiences a very different type of legal drama and I can't wait to introduce them to it."

"As she delves deeper into the case, and suspicions grow around her daughter's new bad-boy boyfriend, Sonny Higgins, Claire uncovers a web of criminal activity that could put her and her family at risk.

"As the truth emerges and consequences unfold, Claire must confront her own biases and decisions. The lines between right and wrong become blurred, leaving Claire in muddy waters as her maternal instincts clash with her commitment to uphold the law."
