Planning on replacing eight prominent world leaders with genetically engineered clones, industrialist Adrian Malprave kidnaps them from a G8 summit in the Mediterranean held aboard the British aircraft carrier, HMS Excalibur. When James Bond's intervention leads to the destruction of the replicants, Malprave holds them captive at her fortified mountaintop facility in the Swiss Alps. There, representatives from four unidentified nations are kept in the base's missile control room, whereas the British and French Prime Ministers, along with the German Chancellor and American President, are all held at gunpoint in four sealed ICBM missile silos. With help from his CIA liaison Zoe Nightshade, 007 infiltrates the facility and rescues the heads of state.
