When the activating button for a nuclear launch is lost at sea, it is up to James Bond to retrieve it before it falls into the wrong hands. Roger Moore once again plays 007 in this, the 12th Bond outing, director John Glen's first Bond film and the first without an Ian Fleming credit. Highlights include a climb up a sheer rock-face; a car chase down a steep, winding mountain road; an underwater battle; and what might be the greatest of all Bond's celebrated ski chase sequences.
