On Bolshoy Solovetsky Island, on the shores of the White Sea, there are old rickety huts. In winter, no one lives in them, because there is no water, no electricity, no communication. But in the summer, people from all over the country come here who want to earn money. These people, day after day, seven days a week, go by boat to the sea. And they return with an unusual catch. For those who are smarter, he is rich. And some even come back empty-handed. But catching is not the point. There is still a lot of hard work ahead.
