Kievan Rus, late 10th century. After the death of his father, Svyatoslav I, ruler of Kievan Rus, the young Viking prince Vladimir of Novgorod (
Danila Kozlovskiy) is forced into exile across the frozen sea to escape his treacherous half-brother Yaropolk (
Aleksandr Ustyugov), who has murdered his other brother Oleg (
Kirill Pletnyov) and conquered the Viking territory of Kievan Rus. The old warrior Sveneld (
Maksim Sukhanov) convinces Vladimir to assemble a Varangian armada, hoping to reconquer Novgorod from Yaropolk and ultimately face the mighty Byzantine forces.
