Synopsis
One particularly hot evening Tintin is out walking with his dog Snowy. Tintin then notices an extra star in the Great Bear. When he reaches home, he calls the observatory. They say that they have the phenomenon under observation and hang up. From his window, Tintin sees that the star is getting bigger every minute. He walks to the observatory and, after some trouble, gets inside. He meets a man called Philippulus who proclaims himself to be a prophet and tells him that "It is a Judgement! Woe!" Puzzled, Tintin proceeds to the main room with the giant telescope. There he meets the director of the observatory, Professor Decimus Phostle, who explains that the extra star is a meteor, a vast ball of fire making its way towards Earth, which will cause the end of the world tomorrow morning.
In the end, however, the shooting star does not collide with the Earth, but passes by it. A piece of it, a meteorite, lands in the Arctic Ocean, causing an earthquake that lasts a mere few seconds. After an analysis of a spectroscopic photo of the meteorite, Phostle deduces that it is composed of an entirely new metal. He names this metal "Phostlite", but is dismayed to discover that the meteorite has landed in the sea and therefore, presumably, is lost. Tintin, however, realises that the meteorite could be protruding above the surface of the water. The Professor is persuaded to organise an expedition to find the metal and to retrieve a sample of it for further research. The expedition consists of leading scientists, as well as Tintin, Snowy and their friend, the alcoholic Captain Haddock (ironically serving as president of the Society for Sober Sailors), aboard the trawler Aurora.
However, unknown to the Aurora expedition, another team has already set out aboard the polar expedition ship Peary, backed by a financier from São Rico, Mr. Bohlwinkel. The expedition becomes a race to be the first to land on the meteorite. Bohlwinkel attempts to sabotage the Aurora expedition by getting a henchman to plant a stick of dynamite on the ship on the eve of departure, but it is found and thrown overboard. While crossing the North Sea, the Aurora is almost rammed by another of Bohlwinkel's ships, but Haddock manages to steer his ship out of the way. Further setbacks occur at the Icelandic port of Akureyri, when Captain Haddock is informed that there is no fuel available. He is furious, but then he and Tintin come across an old friend of his, Captain Chester, who reveals that there is plenty of fuel and that the Golden Oil Company (which has a fuel monopoly) is owned by Bohlwinkel. The three of them devise a plan to run a hose from Chester's ship, Sirius, to the Aurora and thus trick Golden Oil into providing them with the fuel they need.
Coming close to catching the Peary, the Aurora then receives an indistinct distress call from another ship and has to turn round in order to help. Inquiries by Tintin lead him to realise that the distress signal is a fake designed to further delay them. Resuming the journey, they then intercept a cable announcing that the Peary expedition has reached the meteorite but not actually claimed it yet. Tintin uses the ship's seaplane to parachute on to the meteorite and plant the expedition flag, beating the crew of the Peary by seconds. The Aurora expedition has won the race.
Tintin makes camp while the ship's over-exerted engines are repaired. The next day he discovers the remarkable properties of Phostlite: his apple core instantly grows into an enormous tree full of oversized apples, and a maggot turns into a massive butterfly. Tintin is menaced by a giant spider and huge, exploding mushrooms before rescue arrives. Then a sudden seaquake shakes the meteorite to its core; the young reporter and Snowy retrieve a rock sample and jump to safety as the meteorite sinks into the sea.
The triumphant expedition's return is reported on the radio. Bohlwinkel listens at first in frustrated silence, but then gets concerned at the news that law enforcement agencies are closing in on him over his attempts at destroying and delaying the Aurora. Back on the ship itself, as they prepare to dock, the Captain announces that they are short on one vital commodity—whisky.
