Christmas 1974, and two young climbers stumble across an abandoned house in the Scottish mountains. It’s a bothy - a safe shelter for hunters and climbers out in the wilds of the highlands. But Phil and Jimmy are about to experience the most terrifying night of their lives, alone in the middle of nowhere.

Is a violent spirit determined to drive them out into the freezing night? Years later, Phil tells Danny Robins his story and about how he researched the house, discovering others had had similar experiences there. What's going on? Danny investigates.
