The In-Laws is a dramedy that takes place at a wedding reception after a ceremony during which the sacramental “yes” was not uttered. But since the guests are already here, and some have traveled a long way, it’s only polite to at least invite them to lunch. The parents of the almost-newlyweds meet in the back of a wedding venue. This is their story. They come from two different worlds, different social strata. Małgorzata and Andrzej, the groom’s parents, belong to the Polish upper class. They are well educated and wealthy. One might even call them “bourgeoisie”. Wanda and Tadeusz, the bride’s parents, are simple, uneducated, working-class people, who are also much poorer. At first, both couples are in shock. Weronika and Łukasz, despite coming from different social backgrounds, seemed to be happy and in love. What happened? Why did Łukasz changed his mind? Maybe he’s seeing someone else? Weronika’s parents want to find out the truth, as do Łukasz’s. Who is at fault here?
