Thunderball finds James Bond matching wits with the sinister espionage organization S.P.E.C.T.R.E, (which stands for Special Executive for Counterintelligence, Terrorism, Revenge and Extortion). This time, S.P.E.C.T.R.E. hijacks a NATO nuclear bomber, hiding the bombs under the ocean depths and threatening to detonate the weapons unless a ransom of 100,000,000 pounds is paid. The mastermind behind this scheme is international business executive Emilio Largo (Adolfo Celi), who maintains a pool full of sharks for the purpose of eliminating enemies and those henchmen who fail to come up to standard. Dispatched to the Bahamas, lucky Mr. Bond enjoys the attentions of three nubile ladies: Largo's mistress Domino Derval (Claudine Auger), British spy Paula Caplan (Martine Beswick, previously seen as a gypsy girl in the 1962 Bond epic From Russia With Love) and enemy agent Fiona Volpe (Luciana Paluzzi).
