October 14, 2025

S4C has commissioned a second season of the critically acclaimed psychological thriller Cleddau (The One That Got Away). Filming will begin in the autumn, with the new season set to air in 2026.   

The emotionally charged drama is once again produced by Blacklight (part of Banijay UK)  and 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.

Season one introduced audiences to DI Ffion Lloyd (Elen Rhys) and DS Rick Sheldon (Richard Harrington), ex-lovers forced to work together to solve the murder of a nurse in a quiet Welsh coastal town – an investigation that unearthed dark secrets from the past with devastating consequences.

Elen Rhys (The Mallorca Files) and Richard Harrington (Hinterland) will reprise their roles in Season two, which follows another complex, twisted and nail-biting case. When a body is discovered in Cleddau River the team suspect a killer is stealing identities and luring women to their deaths through a dating website – one that Ffion herself has been using as she tries to move on from Rick, despite the fact he is now separated and single…

It’s a gripping and emotionally intelligent series that showcases the very best of Welsh talent, both on and off screen. We are thrilled to bring the story back for a second season and deepen the world that Cath Tregenna has so brilliantly created.”
