Sleepwalkers revolved around Dr. Nathan Bradford who is the head of the team that had developed a technology to enter the dreams of psychiatric patients to discover what their true problems were. He also uses the machines to enter the unconscious mind of his wife, Gail Bradford, who is in a coma. The other members of the team are Kate Russell, the scholar of the group, with a vast knowledge of mythology and archetypes from many religions and Vincent Konefke is the technical guy who ran the machines but never dreamwalked himself. Steve Turner is the other sleepwalker.

In the near future, civilisation has broken down to the barest fragment of recognisable life. Young people are forming gangs and dominating the wrecks of cities like London. But the strangest Earth-children are the Planet people, following plumb-bobs to sacred sites, waiting to be "Taken Up". Professor Quatermass, seeking his granddaughter, teams up with Joe Kapp, who is trying to analyse strange signals from space using the last working pieces of electronic equipment. They find the Planet People at a nearby stone circle, a light appears, the signal appears, - and the hippy children are gone. Russian plot? Nirvana? Or something altogether more sinister?

A Norfolk village, Sweethope, slides into the sea - but miraculously, there is no loss of life. One of the villagers, Philip Gates becomes a Chief Superintendent and is put in charge of several cases where prominent individuals are killed but are then resurrected. Photographer Steve Blake and his ex-wife Joanna Ball stumble across something far more sinister than miracles. When they make contact with Gates wife Melissa she explains that since that fateful night at Sweethope, her husband had never been the same since. Leading to conclusions that whatever was behind these happenings, was not human.

Dead of Night was a British television anthology series of supernatural fiction, produced by the BBC and broadcast on BBC2 in 1972. It ran for a single series; of its seven 50-minute episodes, only three—"The Exorcism", "Return Flight", and "A Woman Sobbing"—are known to survive in the BBC's archives. Another programme made by the Dead of Night production team under Innes Lloyd, The Stone Tape, intended to be the eighth episode, does survive in the archives but was not broadcast under the Dead of Night banner.
