X: The Unknown1956

Horror Vault's take

Deep beneath the Scottish highlands, military exercises disturb something ancient and ravenous — a force that feeds on radioactive energy and leaves its victims horribly burned. As a trail of mysterious incidents fans out across the countryside, an American scientist and a British investigator must race to understand what they are dealing with before it reaches the next source of power. A product of 1950s atomic-age dread, this Hammer production channels genuine unease from its remote, fog-shrouded setting and a threat that resists easy comprehension.
