Is a party after a canceled wedding a recipe for disaster? It is. And what a disaster it is! Two families differ in everything - origin, status, wallet content, taste. The parents of the groom and bride are initially shocked. What did such a thing happen? Who was at fault? What about the wedding party? Should they welcome the guests? Play music? Pour the vodka? Who will cut the cake? From word to word, polite smiles turn into public washing of dirt. And finally a real bomb goes off... And in the meantime, the wedding party turns into a wild party. And no one is bothered by the absence of the newlyweds.
Unfortunately the movie The In-Laws is not yet available on HBO Max.
