Diamonds Are Forever

In the pre-title sequence, James Bond is pursuing Ernst Stavro Blofeld who was responsible for the death of his wife. After interrogating several of Blofeld's associates worldwide, Bond traces him to a facility where he is surgically creating look-alikes. Bond kills a test subject who is lying in a mud bath. Bond manages to drown the man, but is captured by Blofeld. After a fight, Bond kills Blofeld by throwing him into a pool of superheated mud.

Suspecting that South African diamonds are being stockpiled to depress prices by dumping, and convinced that Blofeld is dead, M orders Bond to replace a diamond smuggler named Peter Franks and unveil his associates. Meanwhile, Blofeld's henchmen Mr. Wint and Mr. Kidd systematically murder several diamond smugglers to cover up their trail. Posing as Franks, Bond travels to Amsterdam to meet a smuggler, Tiffany Case, at her apartment. However, Franks escapes from custody and reaches Case's apartment. Bond intercepts and kills him after a fight in a lift, then switches wallets to make Case think James Bond is dead. The two then smuggle fake diamonds to Los Angeles within Franks' corpse.

At the airport Bond meets his CIA ally Felix Leiter and transports the body to Slumber Inc., a funeral home where another smuggler, Shady Tree, quickly realises that the diamonds are fake. Bond tells Leiter to ship the real diamonds while he heads for Las Vegas where Tree works as a stand-up comedian; however, Tree is killed by Wint and Kidd. Later in the casino, Bond meets a girl named Plenty O' Toole and takes her to his room, but she is shortly evicted (out the window and into the hotel swimming pool) by the smugglers, who have come for the real diamonds. Instead, Bond spends the night with Case, who has been waiting in the suite's bedroom in order to get him to talk about the true location of the diamonds. Bond sends her to retrieve the diamonds at a circus, but she loses her watchers despite the proclaimed fool-proof surveillance by Leiter and the CIA.

Bond reveals his identity to Case when the latter returns to her operation residence and finds the body of Plenty, who was mistakenly killed by Kidd and Wint. Having survived the attempt on her life, the initially reticent Case decides to assist him in his mission. Posing as a lab worker, Bond enters the apparent destination of the diamonds – a laboratory owned by reclusive Las Vegas millionaire Willard Whyte, where he finds laser refraction specialist Professor Dr. Metz constructing a satellite. He flees by stealing a moon buggy and reunites with Case in a car chase with security and the local police. They return into town where Bond scales the walls to the top floor of the Whyte House. Inside, he is disarmed and confronted by two identical Blofelds who are posing as Whyte using an adapted telephone to mask their voice — Bond had previously killed a look-alike. Not knowing which to kill, Bond kicks Blofeld's cat into the arms of its owner and shoots him. However, the cat also turns out to be a look-alike.

Bond is rendered unconscious and then left inside a pipeline by Wint and Kidd. He escapes and contacts Blofeld, posing as one of Whyte's employees and Blofeld's middle-men, Bert Saxby. Learning about Whyte's penthouse, Bond goes there and fights the bodyguards Bambi and Thumper, forcing them to tell him where Whyte is. The latter is rescued, but Blofeld abducts Case. With the help of Whyte, Bond raids the lab and uncovers Blofeld's plot to create a laser satellite using the diamonds, which is now in orbit. Blofeld destroys nuclear installations in the United States, Russia, and China, then proposes an international auction for global nuclear supremacy.

Bond identifies an oil rig off the coast of Baja California as Blofeld's base of operations. Arriving at the rig, he switches the cassette containing the codes which control the satellite with a music tape, giving the coded one to Case who is living there as a hostage. However, trying to be helpful, she switches the tapes back. As Blofeld plans to attack Washington D.C. using the satellite, Whyte and Leiter lead an air assault on the base. Blofeld tries to escape on a mini-sub, but Bond gains control of it, and crashes the sub into the control room, destroying the satellite control along with the rest of the base.

Bond and Case then head for home on a cruise ship, where Wint and Kidd also board disguised as waiters. Bond sees through their disguise, and kills them. The film ends with Tiffany wondering about how to get all the diamonds from the laser satellite back down to Earth.
