Auric Goldfinger enlists the help of Pussy and her Cement Mixers to carry out "Operation Grand Slam", a scheme to kill all the soldiers guarding Fort Knox by poisoning their water supply with a water-borne nerve agent (GB, also called sarin), and then to use a nuclear weapon which he had purchased from a quartermaster storekeeper at an Allied military base in Germany for one million dollars to blow open the United States Bullion Depository and contaminate the one billion dollars of gold stored there with the nuclear bomb to make it radioactive, which will vastly increase the value of his gold holdings. Goldfinger chooses the Cement Mixers because he needs a group of women to impersonate the nurses in the fake emergency medical teams he plans to send into the poison-stricken Fort Knox.
