The daily life of Marina Burtseva from the provincial town of Rybatsky is not very different from the lives of thousands of the same ordinary girls living in the hinterland of a large Soviet country. Her father breaks down under the blows of fate – first the death of his wife, then the loss of work – and slowly sings from the futility and meaninglessness of his existence. And when there is an opportunity to earn on his own daughter, without thinking, he sells Marina to earn money in the city. But having a strong character, the girl does not give up.

Marina's life is a series of difficult tests. Being a sold own father, deceived by a loved one, betrayed by friends, having lost faith in others, will she be able to find reasons to continue living, to fight for her future, to forgive and to love again? How many trials can one person suffer and what is the price of happiness? For the heroine of the series, reflections on this subject are not rhetorical searches for the meaning of life, these are questions that she has to answer every minute to survive.
