According to one of the Chinese legends, a thousand years ago the king of snakes gave the Beautiful Empress Xiao Lin an unusual bracelet - a thin golden snake with emerald eyes biting its tail. Called the Ring of the Serpent, this bracelet gave its owner the secret of eternal life, because it contained the blood of the immortal Phoenix bird. But when the Beautiful Empress Xiao Lin saw the first wrinkle in the mirror, she realized that eternal life does not mean eternal youth, and committed suicide. The secret of the Serpent Ring was lost for centuries, and only today traces of the missing relic have been discovered in Russia. An ordinary housewife, Nadezhda Lebedeva, was involved in the pursuit of the artifact. Bit by bit, she collects information about the sacred amulet and is getting closer to solving the mystery of the Beautiful Chinese Empress.
