An owner of a music shop, Arkady Ivanov, sets out to find treasures of the Hunnic ruler Attila and travels to Hungary. The search for the treasure leads him far back into the past—to the fifth century. Attila is dead, but his followers and enemies persistently fight over power, while black priests gather to offer up a beautiful girl from 1956—one with pearl-like hair—whom our hero falls in love with. To save his beloved, Arkady will have to go through a great deal—both in modern times, and in the fifth century, and in 1956, during the famous anti-Soviet uprising in Hungary.
