First-look images unveiled for highly anticipated second series of Cleddau

S4C has released a first look at the return of Welsh hit drama Cleddau, which will air on S4C, BBC iPlayer and S4C Clic in October 2026. The six-part second series sees DI Ffion Lloyd (Elen Rhys) and DS Rick Sheldon (Richard Harrington) return as they hunt a killer who uses a dating app to stalk his victims.

The new pictures, released during the Pembrokeshire County Show, showcase the Pembrokeshire coastline which serves as a breathtaking backdrop to the drama’s location. Returning cast include Mali Ann Rees (DC ‘Mogsy’ Morgan) and Aled Pugh (DS Celyn Howells). Also returning are Sharon Morgan (Delyth Lloyd), William Thomas (Griff Lloyd), Rhian Blythe (Helen Sheldon), and Hannah Daniel (Lisa Redwood). New cast for series two include Saran Morgan (DC Catrin Duffy), Garmon Rhys (Tom Danbridge), Mabli Jên Eustace (Manon Grant) and also Gareth David-Lloyd (Liam Floyd).

The first series of Cleddau was a major success for S4C in 2024, achieving the highest average viewing sessions of any non-sport and non-children's series on the service and earning an Audience Index score of 86.

Cleddau won Best Drama at the RTS Cymru Wales Awards in 2025 and was also nominated in four other categories at last year’s BAFTA Cymru Awards, including Elen Rhys for Best Actress.

Cleddau (6x50’) series two is written and created by Catherine Tregenna and adapted into Welsh by Hanna Jarman and Matthew Glyn Jones. The executive producers are Philip Trethowan and Ben Bickerton of Blacklight, and the series is directed by Siôn Ifan.

Both Cleddau and Cleddau 2 have received support from the Welsh Government via Creative Wales

Mared Swain, the show’s producer, says:

"We were delighted by the response to the first series of Cleddau, from audiences in Wales and beyond. The story, characters and world Catherine Tregenna created left us with so many possibilities to explore, so we're thrilled to be bringing viewers a second series.

"It has been a privilege to return to Pembrokeshire with our cast and crew, and we're incredibly grateful to S4C, particularly Gwenllian Gravelle their Head of Film and Drama, for their continued support and belief in the project. We can't wait for audiences to join Ffion and Rick on another gripping and unexpected investigation this autumn."

The series is filmed back to back in both Welsh and English, with the English version titled The One That Got Away. The series will be distributed globally by Banijay Rights, the global distribution arm of content powerhouse Banijay Entertainment. The production is supported by the Welsh Government via Creative Wales.

Series two of Cleddau will be coming to S4C and BBC iPlayer in October. Series one can be streamed on S4C Clic and BBC iPlayer.
