Vasya slyly leaves a book recounting Vrungel’s past adventures in his kiosk and then visits his friend Lom, a former first mate now working as a bathhouse attendant, showing him newspapers about the Bermuda Triangle.

When the day of departure arrives, Captain Vrungel delivers a speech but accidentally damages the side of his yacht, "Victory," causing the first two letters to fall off, transforming its name to "Trouble."

However, the expedition catches the attention of an elderly businessman and president of the foreign "Want and Sons Company," Sir Want, who fears Vrungel’s voyage threatens his corporation’s survival.

Despite several attempts by Harry to disrupt the journey, Vrungel, Lom, and Vasya persevere, eventually reaching Sir Want’s city, where they discover a soulless metropolis filled only with machines, pollution, and artificial nature.

Vrungel’s crew sails onward to solve the Bermuda Triangle’s mystery, encountering strange phenomena until they are transported back to a TV studio where Vasya, now a renowned scientist, explains the disappearances as an elaborate hoax by Want’s corporation.
