Another story of a big family whose life is full of problems and unexpected changes. Barbara and Lucjan are about 60-years-old. They have three daughters and one son. But the truth is that the oldest one, already married and having two sons (who are twins) is not Lucjan`s daughter. When a bad sister-in-law tells her it it`s like a storm over the family. And it`s only an example taken from a complicated life of the Mostowiaks family. With each new episode (there are more than 200 of them by now) there are more things happening. The Mostowiaks` children know how to make their lives not boring for those who watch.
