Tráthnóna amháin, feiceann Tintin solas geal sa spéir – dreigít ag titim i dtreo an Domhain. Tuirlingíonn cuid den dreigít sin gar don Mhol Thuaidh. Téann Tintin, an Captaen Haileabó agus criú eolaithe ann chun teacht ar an réalta reatha. An mbeadh mianraí luachmhara inti? Cuireann an dreigít an-iontas ar an iriseoir óg. An chéad rud eile, faigheann an criú amach go bhfuil long eile ag triall ar an Mol Thuaidh!

One evening, Tintin sees a bright light in the sky – a meteorite falling towards Earth. Some of that meteorite lands near the North Pole. Tintin, Captain Halibut and a crew of scientists go there to find the current star. Would it contain valuable minerals? The meteorite amazes the young journalist. Next, the crew finds out that another ship is heading for the North Pole!
