Early one winter morning in the rural town of Rhuthun in North Wales, three men are called upon once again to carry out a terrible assignment on the Bwlch Pen Barras mountain pass.

Shot on 16mm by cinematographer Sean Price Williams (Good Time, Her Smell) and featuring a score by Cian Ciaran and Dafydd Ieuan from The Super Furry Animals, The Wyrm of Bwlch Pen Barras is a Welsh language folk horror film about modern Wales, rooted in the country's rich mythology.
