The Quatermass Conclusion: Part 1 "Ringstone Round"

Chapter One: Ringstone Round
Quatermass (John Mills), now living in retirement in Scotland, travels to London in search of his granddaughter, Hettie Carlson (Rebecca Saire), who has gone missing. He is shocked by the scale of the urban collapse that has struck the city – law and order has broken down and marauding gangs terrorise the litter strewn, decaying streets. Appearing as a guest on a television programme covering the "Hands in Space" project, a joint space mission between the United States and Russia, Quatermass is horrified when the two spacecraft are destroyed by some unknown force. Astronomer Joe Kapp (Simon MacCorkindale), another guest on the programme, invites Quatermass to join him at his home in the country where he has constructed a radio telescope. At the radio telescope, Kapp's colleagues report that they detected a powerful signal at the exact time of the incident in space. Quatermass is intrigued by the behaviour of a group of hippie-like youngsters known as the 'Planet People' who are travelling to various Neolithic sites where they believe they will be transported to a better life on another planet. Quatermass suspects Hettie has joined them. Along with Kapp's wife, Claire (Barbara Kellerman), Quatermass and Kapp follow a group of Planet People to a stone circle of megaliths; 'Ringstone Round'. As they watch, the Planet People assembled inside the circle are bathed in a bright light and disappear, leaving only a residue of white dust.
