After learning that she was an adopted daughter, Nadezhda began searching for a biological family and, as it seemed to her, found sisters. But a genetic test has disproved their relationship. The editors of the DNA program conducted their own investigation and came to a resident of Kazakhstan, who claims to know the secret of Nadezhda's birth. Is it possible that a woman at the age of 32 will see for the first time the biological parents who gave her life?

Worried that it was not her mother who was buried in a closed coffin, Tatiana insisted on a genetic examination and the result turned out to be zero. Then Tatiana passed the test with her father and, to the horror of her relatives, it also turned out to be zero. Why, at the age of 45, did a woman turn out to be not native to either mom or dad? And what will the test be like with your sister? The secret of adoption or another substitution in the hospital?
