Scientists search for the origin of a mysterious capsule found buried in a London building site.
This serial has been cited as having influenced Stephen King and the film director John Carpenter.
Roney calls in his friend Professor Bernard Quatermass of the British Rocket Group to prevent the military from disturbing what he believes to be an archaeological find. Quatermass and Colonel Breen, recently appointed to lead the Rocket Group over Quatermass’s objections, become intrigued by the site. As more of the artefact is uncovered additional fossils are found, which Roney dates to five million years, suggesting that the object is at least that old. The interior is empty, and a symbol of six intersecting circles, which Roney identifies as the occult pentacle, is etched on a wall that appears to conceal an inner chamber.
