Nick Andrews, Head of Commissioning for BBC Cymru Wales, added: "The One That Got Away is a knotty, twisty-turny, edge-of-your-seat thriller interwoven with an electrifying love story, featuring a fantastic Welsh cast.
BBC One Wales will premiere The One That Got Away on February 25 at 9:10pm, and the full series will hit iPlayer on the same date for viewers outside of Wales.
The One That Got Away features Welsh actors Elen Rhys, known for her role in The Mallorca Files, as DI Ffion Lloyd, and Richard Harrington from Hinterland as DS Rick Sheldon.
Set against the beautiful backdrop of south Wales, The One That Got Away is based on a Welsh-language drama titled Cleddau which was made for S4C.
The BBC is set to drop a gripping new psychological thriller next week, filmed in the scenic landscapes of south Wales and centred around the hunt for a murderer in a quaint town.
