They have barely arrived back on earth from their moon adventure when Tintin, Captain Haddock and Snowy are caught up in a tale of intrigue and espionage. Professor Calculus has invented a machine capable of destroying objects with sound waves. Although the machine is only at a prototype stage, it has already come to the attention of the Bordurian secret services. Borduria is a fascist country ruled by a dictator named Marshal Kûrvi-Tasch.
