A mother with many children wanted to prove to her husband that while he was in prison, she gave birth to his son. But the DNA test showed: she cheated. Now the woman claims that the father of the child is her ex—husband. But there is also a new husband who wants to know if he is raising his son. Who are the dads of three children?

The father decided on the fourth genetic examination with the long-awaited son. The man does not know what result to believe, so he turned to the DNA program. His ex—wife desperately proves that the positive test conducted on her initiative is accurate, and the two negative ones conducted by the ex-spouse are erroneous. On whose side will be the most authoritative genetic examination in the country?
