The Mongol Khan entrusted the famous traveler Marco Polo with a special insignia - a gold plate "paiza". The owner of the paizi had special powers and could count on any help and protection in the empire of the great khan. Marco Polo's record was unique and inimitable; it was this that he used to preserve the Khan's unimaginable treasures - tribute from the surrounding lands. The treasure has not yet been found, because the golden talisman disappeared many centuries ago... Sonya, suffering after the betrayal of her beloved, did not want to go to Greece at all, and soon the girl was convinced that she had in vain agreed to her friend’s persistent persuasion.

But for some reason Sonya doesn’t want to part with the souvenir, despite the fact that the strangers do not intend to retreat. They are ready to take possession of the record, even if they have to kill everyone who dares to stop them...
