He and Tiffany go to find out where the diamonds are going to and find it is a research facility in the desert. He finds that Blofeld has kidnapped Whyte and is pretending to be him. His plan is to turn all those diamonds into a big laser in space and blow things up. Bond escapes and alerts the CIA who goes and frees Whyte. He is on an oilrig in California.
Bond has to switch the tape which controls the laser.
There is a huge battle scene with helicopters and the people on the oilrig. Bond escapes with Tiffany, the oilrig blows up, the world is saved, all by Bond. I thought it was pretty good, not awesome, but pretty good. There is a very good climax to the movie with lots of action. The opening song is good, but there are certain parts I don't like.
