USSR, early to mid-20th century. After the October Revolution of 1917, two families, the Skolchins and the Ermakovs, once friends, end up on opposite sides of history. But two of their children will find love and life together.
For many years, separated by a river, two large families coexisted in a remote Ural village: the Skolchins and the Ermakovs. After the revolution, they found themselves in two irreconcilable camps. But their children fell in love with each other, and the fates of the descendants of these two families were intertwined into a hard ball.
