Automobile engines were struck by a strange epidemic: they suddenly began to explode for no apparent reason. The newspapers in vain shout about the disaster: the shares of oil companies are rapidly falling, the wells are closed, the air transportation is curled up due to poor quality fuel... Specialists do not leave the laboratories, but they cannot find an explanation of the mysterious phenomenon, because the methods of oil production and processing remained the same; The fuel samples also did not give anything...

so, maybe this is someone's evil intent? If so, who is behind him? Tintin is taken to answer all questions and reveal the secret of exploding gasoline. To do this, he is hired by the radio operator to the Apdel Star Tanker, sailing to Khemed Arabia - a country of black gold.
