ДНК S04E109 - Выпуск 513. Кого с кем подменили?

A friend told a resident of Germany that a woman who looked like her friend's mother in her youth got a job for her. After hearing a request for a genetic examination, the family of the same woman remembered how they were given a girl in the hospital, although they came to meet the twins. Now both families want to know for sure, if there was a substitution in the Kabardino-Balkaria maternity hospital, then who and with whom?
