The crime drama stars Elen Rhys and Richard Harrington. 

The BBC have acquired a new, six-part thriller The One That Got Away, filmed and set in Pembroke Dock, Wales.

The show is the English language version of Cleddau, an original series for Welsh language broadcaster S4C. It stars Elen Rhys (Consent) and Richard Harrington (Hinterland).

Here’s the synopsis:

The One That Got Away is a psychologically driven thriller in which DI Ffion Lloyd (Rhys) partners up with her ex-lover DS Rick Walters (Harrington) to find out who is responsible for murdering a nurse in a Welsh coastal town. The murder opens old wounds in a small-town community, throwing a historic conviction into doubt and raising the horrifying prospect of a copycat killer. It is a forensic examination of a town, a killer, and a relationship, past and present.

Produced by BlackLight TV, the writer is Catherine Tregenna (Torchwood, Doctor Who, Bergerac).

Sue Deeks, Head of BBC Programme Acquisition, says:

“The One That Got Away is a deliciously dark and atmospheric thriller – sure to keep BBC viewers gripped to the very end…”

The show will air on BBC Four, as well as BBC Wales and the iPlayer.
