ДНК S08E57 - Выпуск 1092. Подмена, измена или родная?

The younger sister was amazed from childhood that the eldest did not look like anyone in the family. Now her main fear is that they may not be sisters to each other at all. But the older sister suspects that there was not a substitution, but treason, saying that her mother gave birth to her not from her husband, but from another man. Substitution or betrayal? Whose side is the truth on? Or maybe both sisters are wrong?
