Ghostlore, folkloric patterns, and science collide in the tale of the infamous Mulmur Hills poltergeist. In the aftermath of the Great War, the Dobson family retreats to a quiet farm in Mulmur Township, seeking peace from urban life. Their tranquility is shattered when terrifying horse mutilations signal the presence of an unseen thing.

The Dobsons flee after years of terrifying disturbances, but their ordeal captivates newspapers, drawing journalists and thrill-seekers to the now-famous "Spook Farm." As rumours swirl about family intrigue, buried secrets, and occult influences, Ivan Hutchins, a Toronto-based spiritualist and investigator, joins the Dobsons to unravel the mystery through seances and investigations. The story unfolds against a wider tapestry of rural Canadian poltergeist cases, comparing the Dobsons' ordeal with other forgotten hauntings and the folkloric patterns they share. This true story reclaims a forgotten chapter of Canadian paranormal history while exploring why such occurrences echo through our folklore, our fears, and our enduring fascination with the unexplained.
