Misfortune never comes alone. A mother abandons three children and runs off with her lover, but fate cruelly punishes her, leaving her crippled with no hope for a bright future. Caring for her and for two brothers falls on the shoulders of the eldest daughter. The girl doesn’t despair—especially when the one she meets on her way cares for her and wants to be near. But happiness didn’t last long: the father learns that the girl’s boyfriend is the son of Strakhov, and separates them. Two years later, Irina meets Sergey again—but this meeting turns into another tragedy: the father disappears. The girl blames herself and decides that she will never see him again. But years later, they meet once more. The new commercial director is none other than Sergey Strakhov. Irina is at a loss, but hopes the man will accept her choice, because she is marrying his brother.
