During a rural gathering near Cassilis in Scotland, villagers celebrate Halloween as a sacred night when supernatural beings are believed to roam the moors. Led by Jock Muirland, a widowed farmer known for his strength, skepticism and heavy drinking, the community prepares food and whiskey while recounting local beliefs about fairies, gnomes and “spunkies.” The harsh, desolate landscape of hills and ruins is portrayed as both threatening and sacred, reinforcing superstition. Although many villagers fear the invisible forces said to be active at night, Muirland mocks these fears and encourages drinking and merriment. Yet the atmosphere remains tense, as tradition holds that at midnight the boundary between human reality and the supernatural world dissolves completely.
The villagers engage in traditional divination games to predict marriage and fate. They uproot the first plant they touch in the “kail” ritual to interpret their future spouse’s appearance, and blindfolded girls gather grain in the “tap-pickle” ceremony to judge moral destiny. They also burn paired hazelnuts to see whether lovers will remain united or separate. These customs mix playful social entertainment with deep-rooted superstition, creating both laughter and anxiety. Despite Muirland’s continued skepticism and drunken mockery, the rituals intensify the group’s sense that unseen forces are present.
When no one dares perform the final mirror ritual, Muirland attempts it himself. With a candle before a small mirror, he calls for his destined spouse and immediately sees a pale female face appear over his shoulder. The apparition persists after the mirror breaks, attaching itself to him as an invisible presence visible only when he turns away. Terrified villagers flee as the night turns stormy, and Muirland becomes convinced he is being followed by a supernatural being he cannot escape.
In a violent storm, Muirland is driven through a distorted landscape toward the ruined cathedral of Cassilis, which transforms into a hellish temple filled with demons, skeletons and grotesque ritual scenes. Surrounded by blasphemous ceremonies and chaotic music, he is led to a dark altar where a skeletal officiant conducts a forced wedding. There he is joined with a beautiful young woman whose face matches the spunkie apparition. Overcome by terror and confusion, he collapses during the ritual.
He later awakens in his farmhouse after several days, told he has returned from the mountains with a wife now lying beside him. Unable to distinguish dream from reality, he is left uncertain whether the supernatural events were real or hallucinated, and whether his marriage is the result of magic or delusion.
