1973: The whole of a small desert town is inhabited by aliens who have taken on human form. They escaped the disaster that wiped out their planet, but denial & post traumatic stress have erased this from their memories. The TV series, based quite closely on the original film, constructs itself as a phased revelation of their state. Imperfect recollections of life and death on the alien world are seen to be symptoms of what look like new psychological disorders. Dr Bax Fermor, drawn to the desert by convoluted Lacanian flexures in his own personality, understands their situation by an intuitive leap, and becomes town psychiatrist. He must spend the rest of his life taking care of them–some he helps to remember, others he gently encourages to forget.
