The Historical and Ethnographic Expedition of the Association of Northern Navigation on the yacht "Saint Peter" visited the Tersky coast of the White Sea. Long ago, this land became home to Pomors. But now the days of peace and tradition are over. Wild horses roam the streets of the villages, windmills stand in the clearings, bears look after the lighthouses, but the inhabitants almost do not build karbas and almost do not fish. But just as before, there is a place on this earth for new shoots and for ancient graves.

Forgotten Stalinist camps, tragedies of the 90s, love and miraculous salvation. Everything is intertwined in One Day of Vladimir Petrovich. The historical and ethnographic expedition on the yacht "Saint Peter" stopped for one day at the mouth of the Ponoi River on the White Sea.
