Exploring themes of mysticism, folklore and geography that are common in Alan Garner’s novels, Red Shift is a uniquely compelling Play for Today from the golden age of BBC drama. The viewer is taken on a beguiling voyage through English history, spanning three time periods: Roman Britain, the English Civil War and 1970s modern day. Garner’s story follows three troubled young men, who occupy these eras and are haunted by shared visions linked by a common location, Mow Cop in south Cheshire.
