Kirill Vatsura is investigating the murder of his friend, FSB Colonel Nefedov. It becomes known that the officer was eliminated by a powerful criminal group, whose representative is going to sail on a comfortable yacht to Cyprus. And then Kirill comes up with a completely crazy idea: he took Nefedov’s international passport, gave himself a haircut “to match Nefedov’s” and under his name went on board the very yacht that was going on a cruise. The yacht set course for the island. There are the nicest people around Watsura. But one of them is a dangerous person from a mafia clan.
