BBC Four has released a new trailer for Hinterland, a major new bilingual detective drama series set in mid Wales.

Originally broadcast on S4C last autumn, the four-part series begins at 9pm on Monday 28 April on BBC Four.

Having just left the Met police in London for a new life in Aberystwyth, DCI Tom Mathias (Richard Harrington) has hardly had time to unpack before he’s called to the scene of a brutal attack at an isolated chalet in the sand dunes. The victim is believed to be a 64-year-old God-fearing woman Helen Jenkins, but she is nowhere to be found.

The investigation leads him to the remote village of Devil’s Bridge, where Helen Jenkins’ body is found at the bottom of a deep ravine, not far from the site of the old children’s home that she ran for many years. The home was closed 15 years ago, and the building is now a hotel, but the untouched attic reveals a snapshot of a tortured past. Only by unlocking the secrets of the children’s home can Mathias crack the case and reveal the murderer.

Cassian Harrison, Channel Editor for BBC Four, commented: “We’re really excited to bring Hinterland to BBC Four viewers, and alongside forthcoming Irish drama Amber, it represents a fresh new departure for us, showcasing the very best acquired drama from closer to home, on top of the many successful international dramas we already show from further afield.”
