Giving the police the slip, Chris returns to the Tomorrow People’s hideout to tell Stephen and Elizabeth that John has vanished without a trace. Violence on Earth reaches crisis proportions; bearers of blue and green badges are splitting off into violent tribes. War seems inevitable. Aboard a hidden spaceship, John learns from Robert that the badges and the pictures are all part of a plan to harvest the psychic energy of the human race as it goes mad to help incubate the next generation of Robert’s people. Is there a way for these aliens and the people of Earth to live, or must one species die off?
Cast: Elizabeth Adare (Elizabeth), Nicholas Young (John), Peter Vaughan-Clarke (Stephen), Philip Gilbert (TIM), Christopher Chittell (Chris), Nigel Pegram (Grandfather), Jason Kemp (Robert), Simon Merrick (Police Inspector)
Notes: The model of the American space station is a model of Skylab, which was launched in 1973 and occupied by three crews, the third of which was still aboard while this episode was in production, but had departed shortly before broadcast. The idea of warring factions denoted by blue and green accessories would be “borrowed” some 20 years later by an episode of Babylon 5.
