Years pass: Igor is already raising two children with Lyusya. Marina often comes to visit them. It would seem like complete bliss, but Lyusya becomes seriously ill. She starts mixing everything up and forgetting things, and it becomes frightening to leave her alone. The doctors cannot understand why such an illness has struck the young mother.

Meanwhile, her best friend begins stealing from her everything she holds most dear—love, family, and a happy life.
