The preparations come to a head when their young son traps his mum and dad in the apartment with a pair of stilts that have fallen and accidentally bounced between the bathroom and the living room. The parents can't get out and the boy doesn't have the strength to help them. The Rubes-s and their friend are impatiently waiting for guests, so they phone the couple. However, their young son tells them that his parents are locked up. This unfortunate expression arouses suspicion in the Rubes family. Misunderstandings multiply, characters are revealed.
