Overtoun House sits above Dumbarton, Scotland, built in the 1800s and later pressed into service as a hospital during World War II. This film by MFN Productions, narrated by Donny Taylor, traces the estate through its succession of owners and architects before settling on the property's strangest feature: a stone bridge where, over the decades, dozens of dogs have jumped to their deaths in the gorge below. Interviews and location footage lay out the competing explanations locals and visitors have offered, from a haunting tied to the estate's past, to a supposed portal or curse, to the more mundane theory that the bridge's parapets and the scent of mink in the ravine below are enough to explain the pattern. The film does not resolve which explanation is correct; instead it uses the bridge as a way into a broader question about why people reach for supernatural answers when a stranger, simpler one might be sitting in the landscape itself.
