Every year he collected a large tribute from this country and sent it to the ruler. But one day a rebellion arose in those parts, and in order to save the priceless tribute, all the wealth was put into huge chests and hidden in a safe place. Centuries passed, and no one could find the countless treasures. Nowadays, the Russian tourist Sonya, who came on vacation to Greece, unwittingly became involved in the search for the cache. Is it really possible that the inexpensive souvenir she bought at the local bazaar is the key to the location of the treasure?..
