A Drax Industries Moonraker space shuttle on loan to the United Kingdom is hijacked in mid-air and MI6 operative, James Bond, agent 007, is recalled from Africa to investigate. En route in a small plane, on an unrelated case, Bond is attacked by the pilot and crew and is pushed out of the plane by the mercenary assassin Jaws. Bond survives by stealing a parachute from the pilot, whilst Jaws lands on a circus tent.
Bond proceeds to the Drax Industries shuttle-manufacturing complex where he meets the owner of the company, Hugo Drax, and henchman Chang. Bond also meets an astronaut, Dr. Holly Goodhead and survives an assassination attempt via a centrifuge chamber. Bond is later aided by Drax's personal pilot, Corinne Dufour, as he finds blueprints for a glass vial made in Venice. Bond then foils another attempt on his life, using a hunting shotgun to shoot a sniper. Upon discovering that Dufour assisted Bond's investigations, Drax has her killed.
Bond again encounters Goodhead in Venice where he is chased through the canals by Drax's henchmen. He discovers a secret biological laboratory, and by accidentally poisoning the scientists there, he learns that the glass vials are to hold a nerve gas deadly to humans, but harmless to animals. Chang attacks Bond and is killed, but during the fight, Bond finds evidence that Drax is moving his operation to Rio de Janeiro. Rejoining Goodhead, he deduces that she is a CIA agent spying on Drax. They promise to work together, but quickly dispense with the truce. Bond has saved one of the vials he found earlier, as the only evidence of the now-empty laboratory, giving it to M for analysis, who permits him to go to Rio de Janeiro.
In Rio, Bond meets his Brazilian contact Manuela. Drax hires Jaws to finish Chang's job of eliminating Bond. Bond meets Goodhead at the top of Sugarloaf Mountain, where they are attacked by Jaws on a cable car. After Jaws' car crashes he is rescued by Dolly from the rubble, and the two fall in love. Bond and Goodhead are captured by henchmen, but Bond escapes and reports to an MI6 base in Brazil and learns that the toxin comes from a rare orchid indigenous to the Amazon jungle. Bond travels the Amazon River looking for Drax's research facility and again encounters Jaws and other henchmen. Bond escapes from his boat just before it hits the Iguacu Falls, and finds Drax's base. Captured by Jaws again, Bond is taken to Drax and witnesses four Moonrakers lifting off. Drax explains that he stole the Moonraker because another in the fleet had developed a fault during assembly. Bond is reunited with Goodhead; they escape and successfully pose as pilots on the sixth shuttle. The shuttles dock with Drax's hidden space station.
Drax plans to destroy human life by launching fifty globes containing the toxin into the Earth's atmosphere. Before launching them, Drax also transported several dozen genetically perfect young men and women of varying races, to the space station. They would live there until Earth was safe again for human life; their descendants would be the seed for a "new master race". Bond persuades Jaws and Dolly to switch their allegiance by getting Drax to admit that anyone not measuring up to his physical standards would be exterminated (Dolly wears glasses) and Jaws attacks Drax's guards.
Bond and Goodhead disable the radar jammer hiding the station from Earth. The US sends a platoon of Marines in a military shuttle. A laser battle ensues in which Drax's guards as well as his new master race die. During the battle, Bond shoots Drax with a cyanide-tipped dart, then pushes him into an airlock and ejects him into space.
The space station, heavily damaged in the battle, disintegrates. Jaws helps Bond and Goodhead escape in Drax's space shuttle. They too escape the space station as their module breaks away before the station explodes. Before the battle Drax launched three of the globes towards Earth, which Goodhead and Bond destroy from their shuttle.
