37-year-old twins are horrified by their mother's confession: it turns out they are not brother and sister at all. A resident of the Chelyabinsk region claims that 37 years ago she took in a girl and a boy from different families. But the twins refuse to believe that they are strangers by blood. Will the former twins find their relatives?

27-year-old Alla honestly admitted that she herself does not know from which of her two lovers she gave birth to a son. Alexey assures that the boy looks like Mikhail, and Mikhail believes that the child is the spitting image of Alexey. The woman was quite satisfied with her status as a single mother, until the son himself asked where his father was.
