HINTERLAND is noir crime drama set in the scenic, centuries-old town of Aberystwyth, Wales. The area is a natural crucible of colliding worlds - a place where history, myth and tradition come face-to-face with modern life - but its panoramic vistas and quaint facade hide a multitude of sins. Into this realm steps the enigmatic DCI Tom Mathias (Richard Harrington - Poldark), a brilliant but troubled man on the run from his past. Together with his equally intelligent and complex partner DI Mared Rhys (Mali Harries - Foyle's War), Mathias tackles mystifying murder cases that take viewers from the windswept sand dunes of the Welsh coastline to the badlands and beyond.
