When London conservationist Adam and his wife Clare move with their infant son to a remote house near the Irish forest, they quickly find their new neighbors unwelcoming. The discovery of a gruesome “zombie fungus” growing in the house is just the beginning, as the surrounding woods spew forth a terrifying array of folkloric banshees, baby snatchers, and demons. Awash in the otherworldly atmosphere of a dark fairy tale, THE HALLOW cleverly toys with genre conventions while unleashing some of the most nightmarishly terrifying creatures in years.
