"Air Seller". Air currents around the globe suddenly begin to deviate from their usual routes in the direction of a certain point located in the expanses of Yakutia, and atmospheric pressure drops slightly. The head of the research expedition, Grigory Klimenko, and his comrades find a giant air thickening plant hidden in the crater of an extinct volcano, built by a brilliant scientist who planned to blackmail the governments of all countries. If he is not stopped, the world will perish..."Wonderful Eye". Mankind is shocked by the death of the ship "Leviathan", with which the famous scientist Khurges died. Anticipating a catastrophe, the scientist throws a bottle with an encrypted note into the waves, which will later be caught by the crew of the Sergo Ordzhonikidze trawler, where they are testing a new device - a deep-sea "eye" - a prototype of a modern TV. Who will be the first to get to the legacy of the great scientist - the adventurer-gold digger Scott or a detachment of Soviet sailors?
