The woman died in childbirth, and the grief-stricken widower, after asking the consent of the eldest 9-year-old daughter, gave the newborn girl to another family. The eldest cannot forgive herself all her life for having abandoned her sister, and has already found, as it seemed to her, her Luba 126 times. She applied to the DNA program and believes that the genetic examination with the 127th applicant will be positive.

The man's second wife accuses his first wife of having walked all their five children. The ex-wife herself does not deny that there were infidelities, but she gave birth to children from her husband. The man himself calls all the applicants for paternity by name, and is sure that the genetic examination will show that the children are not from him. So who turned out to be a father with many children in reality: a deceived cuckold husband with an experience or a would-be father greedy for alimony?
