Yvette Fielding and the Most Haunted team embark on a triple investigation of three haunted locations, Ruthin Castle, Shrewsbury Prison and Leeds' Armley Mills. The 90-minute-long episode saw Yvette and her husband tackle the ghostly goings in Wales at a 13th century castle in Ruthin. Meanwhile Stuart was alone on the abandoned wings of HMP Shrewsbury, and Glen was hunting spooks at Armley Mills in Leeds. The episode is the fourth to be labeled a 'Most Haunted Extra' and uploaded exclusively to Most Haunted's official YouTube channel.
