No one is closer and dearer to Lera than her younger sister, Natasha, whom she had been bringing up alone since she was 18 years old. In order for her sister never to want for anything, Lera even abandoned her dream of studying medicine.
The sisters have lived in perfect harmony until the day when the younger one decides to leave for the capital city in search of a better life, a decision which drives something of a wedge between them. It even comes later to a confrontation in the fight for the heart of the same man. But, fortunately, both have enough commonsense and sisterly love to avoid a complete break. Lera steps aside so that Natasha can be happy, and soon afterwards fortune rewards her with a new love.
