Mudtown (Ar y Ffin) plot

Set in South Wales, this six-parter, Mudtown (Ar y Ffin) focuses on the goings on at Newport's Magistrates Court, where experienced Magistrate Claire Lewis Jones (Richards) faces personal turmoil while presiding over cases...

Claire, played by Gotham star Erin Richards, is tested professionally when Ned Humphries, her daughter Beca’s childhood friend faces arson charges. Things become more complicated when criminal kingpin Saint Pete (Tom Cullen) arrives on the scene, and Beca (Lauren Morais) starts dating a local bad boy Sonny Higgins (Lloyd Meredith). But as Claire delves deeper into the case, her maternal instincts clash with her commitment to the law and she finds herself embroiled in a web criminal activity that risks everything. Claire and Saint Pete go back a long way - will her past come back to threaten her present?

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."

Mudtown (Ar y Ffin) cast and interviews

The six-part drama Mudtown (Ar y Ffin) boasts an impressive cast, including Erin Richards (Gotham, The Crown), who plays Claire Lewis Jones and Tom Cullen (The Gold, Becoming Elizabeth) as criminal kingpin, Saint Pete. 

Kimberley Nixon plays Sara Humphries (The Salisbury Poisonings, Life and Death in the Warehouse) and Gareth John Bale is Glyn Humphries. Lauren Morais (The Red King) plays Beca Lewis Jones and Lloyd Meredith (The Red King, Gran Turismo) plays Sonny Higgins. 

Matthew Gravelle (Broadchurch, Steeltown Murders) is playing Beca's father  Alun Lewis Jones (see pictured above).

Tom Cullen says: "Saint Pete; he is the local gangster. I think he's described in the script as Newport's Tony Soprano but obviously it's evolved a bit since then. But yeah, he's really smart and an intelligent guy who is a product of his environment."

Lloyd Meredith says: "The first impression we have of Sonny is that he is a stereotypical rough and ready bad boy. But the more we learn about Sonny and delve into his past, the more we realise there’s a lot more to him than that. He’s a complex character and we learn that he’s quite a damaged person. He has a lot of traumas in his life and that makes you feel a little sorry for him. Unfortunately for him, he’s made a lot of bad mistakes and decisions in the past, so he spent some time in Wakefield prison before he moved to Newport, so the story picks up once he’s in Newport and he’s got this new life. But that move has triggered something for him and his whole world has been turned upside down once he meets Beca, falls in love and starts to work for Saint Pete."
