A woman in a car goes crashing over a cliff, a man is pushed over a balcony, a woman shot in the head is made to look like suicide. What do these deaths have in common with a bus accident carrying a load of children in which the bus driver is killed? The nightmares of a child (Gwyneth Strong) that survived the accident may provide the clue that a police detective (Christopher Lee) and a forensic pathologist (Peter Cushing) need to piece together in order to solve the mystery. This dark thriller combines elements of sci-fi and horror and has the same vibe and a certain similarity to the cult classic THE WICKER MAN which actually came out almost a year later but it isn't as successful. The narrative is often incoherent and motivations unclear. Directed by Peter Sasdy (TASTE THE BLOOD OF DRACULA). The impressive supporting cast includes Diana Dors as the mother of the surviving child who knows the dark secret but isn't telling, Georgia Brown as an investigative reporter determined to unlock the secrecy, Michael Gambon, Kathleen Byron (BLACK NARCISSUS) and Keith Barron as the well meaning doctor who discovers no good deed goes unpunished.
