Andrey inherits a map to his great-grandmother's treasure, a gift from her lover, and hidden since the early 19th century. He and Mikhail, the descendant of his great-grandmother's lover, follow the map's clues to Montenegro.

Young Andrey Teleshev (Aleksei Chadov) inherits a cryptic map from his great-grandmother Ekaterina that seems to be the key to finding a hidden treasure, given to her in the early 19th century by her lover, Governor-General Miloradovich. When he is unable to decipher it, he enlists the aid of Mikhail Milodravich (Aleksandr Domogarov), the descendant of the Governor-General. Although initially reluctant, Mikhail joins Andrey, and the two follow the map's clues to Montenegro. Pursued by the larcenous Father Sergiy (Viktor Bychkov), an Orthodox priest who accidentally learned of their secret, and assisted by the beautiful Slavka (Evgeniya Khirivskaya), a mysterious young Montenegrin woman who agrees to join them, Andrey's and Mikhail's adventure will include car chases on winding mountain roads, burglaries, gun fights, stolen backpacks, a desolate abandoned fortress, falling rocks, fist fights, repelling down treacherous mountain crags, a flooded cave, and a boat chase through Montenegro Harbor. Love will bloom, and the treasures that Andrey and Mikhail will each find in the end will not be what they expected.—Anonymous
