X the Unknown is a well-crafted imitation of the Quartermass British sci-fi pictures of the 1950s. A group of soldiers on manoeuvres in Scotland stumble across a gravel pit which emanates an unusual amount of radiation. Several deaths occur before the radioactive material is mysteriously stolen. Researched Dean Jagger speculates that the thief is some sort of inhuman monstrosity dwelling at the Earth's core. He points out that past radioactive disturbances have been occurring at fifty-year intervals, each followed by sudden deaths and the disappearance of the material. Jagger suggests that the unknown monster has been resuscitated by mankind's recent atomic experiments. Sure enough, the monster manifests itself as a huge slab of glowing radioactive mud.
