The head of the Duchy of Moscow, Ivan III, accepts an offer from ambassadors to Rome to marry princess Zoe of the ancient Byzantine Palaiologos family.
He sends voivode Khromoy and monetary master Ivan Fryazin to Rome, who bring Zoe to Moscow, where she takes a new name after rebaptism – Sophia.
The attempts to send emissaries with the aim of urging Sophia to follow the line of Rome and further killing her end in failure.
[6] The decorations of the Moscow Kremlin were built for the filming in the territory of VDNKh, which matched its historical 15th century image (then it did not have the familiar red colour, but was white).
The song Я тебе верю (I Believe You) from the series' opening sequence was performed by singer Grigory Leps.
