Quatermass is rescued by a group of elderly people living in a scrap yard. At the hospital, the doctors are shocked when Isabel levitates off her bed and explodes in a cloud of dust. Elsewhere, the devastated Kapp is left alone in the ruins of his cottage and observatory. More and more young people are joining the Planet People, including the gangs that have been terrorising the cities and the soldiers assigned to keep them away from the Megalithic sites. Contact is restored with Chuck Marshall and with the Russians in the form of Gurov (Brewster Mason). Quatermass theorises that this is not the first time this has happened; Megalithic sites such as prehistoric stone circles are in fact markers where beacons have been left by the alien force for its next visit. Quatermass believes the force is a sphere of energy surrounding the Earth. The Russians and the Americans send a space shuttle, commanded by Marshall, to make contact with the force. Quatermass is sceptical; he believes they are dealing not with an intelligence but with a machine constructed to harvest human protein. The space shuttle is destroyed but not before Marshall reports a giant beam of light stretching in all directions. Meanwhile, the Planet People are gathering at Wembley Stadium in the tens of thousands. Annie and Quatermass travel to the stadium but are powerless to prevent the Planet People from gathering. When they are attacked, Annie drives their car into the underground car park beneath the stadium where she crashes the vehicle and is killed. The lightning strikes the stadium. (thetvdb.com)
