The Chinese theory that life is pre-ordained and that dreams are a glimpse into the future prompts Commander Lindsay (Michael Hordern, Where Eagles Dare) to relate a dream he has experienced to his fellow dinner guests, including Air Marshal Sir John Hardie (Michael Redgrave, The Captive Heart). The dream involves a Dakota aircraft carrying thirteen people, one of whom is Hardie. The plane is lost over the sea, the radio fails, and fuel is running short when, through a break in the clouds, a rock-strewn beach appears and the plane crashes horrifically. Lindsay then starts to live out his nightmare as different pieces from his dream start to fall into place. Are these similarities just coincidences or did his dream foretell the disaster? Ealing Studios veteran Leslie Norman (Dunkirk, X the Unknown) directed this thrilling and mysterious adventure yarn co-starring Alexander Knox (The Psychopath) and Denholm Elliott (The Sound Barrier).
