Diamonds Are Forever

Large quantities of South African diamonds are being stolen but haven't found their way into the world market. It is James Bond's mission to discover who is stockpiling these diamonds and why. He discovers that Ernst Blofeld has constructed a giant laser generator, suspended in orbit around earth, that uses diamonds to intensity its energy causing nuclear warheads, rockets and submarines to spontaneously self-detonate. Blofeld intends to hold an international auction with nuclear supremacy going to the highest bidder. Bond pursues his arch enemy to his oil rig base off the California coast to prove that diamonds aren't just a girl's best friend.
