Radio 1 presenter Sian Eleri investigates a seemingly ordinary farmhouse in north Wales, which, in the late 1990s, was widely considered the most haunted house in Britain. The story made local and national headlines as the family who lived at the farm became ever more desperate in their search for answers. More than 300 allegedly paranormal events were documented at the Flintshire farmhouse in video footage, audio interviews, photos and eyewitness accounts – all of which has been locked away until now.

Sian is frustrated that she still hasn’t been able to contact the Gower family who lived at the farmhouse – David, a former headmaster, his wife Rose-Mary and their son John-Paul. But there is a breakthrough of another kind when the current owner of Penyffordd Farm gets in touch and invites her over to see the house she’s heard so much about.

Sian Eleri’s investigation into the haunting of Penyffordd Farm continues as multiple witnesses claim to have seen a hooded figure. Could they all have imagined the same thing?
