In diamond-producing South Africa, strange things have occurred recently. A large number of uncut diamonds have disappeared and murders have occurred frequently. These abnormalities attracted the great attention of the British authorities, so 007 (Sean Connery) came to South Africa. 007 launched a series of investigations in the name of a diamond wholesaler and found that everything was behind the scenes by his arch-enemy, Ainas (Charles Gray), the leader of the Devil Party. Ainas was not just pursuing money, but an attempt to use these diamonds to make the most lethal laser satellite equipment to achieve his evil goals. So, 007, with the help of the beautiful Bond girl Kansi (Jill St. John), begins the operation to crush this conspiracy!
