Quatermass

Professor Quatermass is resisting planners of a rocket project known as the Dead Man's Deterrent. Meanwhile excavation is going on at Hobbs Lane, reported site of imps and devils.

Col. Breen believes the projectile, which is radioactive and made of an unknown substance, is a bomb. Meanwhile, Roney's assistant Barbara Judd finds the area has a history of supernatural events.

Journalist James Fullalove helps Quatermass research the history of Hobbs Lane, finding its name derives from Hob - the devil. Meanwhile, technician Sladden, succeeds in opening a sealed compartment in the capsule, revealing three petrified alien insects.

Roney and Quatermass develop their theory about the Martians' visit to Earth, instilling their essence into man's ancestors, Sladden, alone in the pit, flees in terror as strange forces are conjured up.

A brain scanner reveals alien pictures in Barbara Judd's mind of 'The Wild Hunt' - the frenetic purging of the Martian hives. In the pit, a technician is killed as the capsule starts to glow.

Chaos reigns in the pit and the long-dormant Martian inheritance begins to assert itself in many people in the area - including Quatermass himself - driving them to a new racial purge. The capsule breaks open and an energy form rises up over London. Roney finds he is immune and strives to defeat it.
