Plot summary
The comedy centres around Peter, a bachelor in his mid-thirties. He desperately wants to win back his girlfriend Jana and asks his friend Midge for help. Midge, another loner unable to form a long-lasting relationship with a woman, has gone through many break-ups and therefore considers himself an expert. Peter also has to visit his discontented parents.

Peter's mother ruined the family with her endless preaching. She has developed a strong passion for blood donation, and is agitated about the war in Chechnya. Peter's father, a former commentator for Communist newsreel, escapes to his own thoughts. He is preoccupied with the idea of whether a light bulb would fit in a mouth. Peter's neighbour, a composer engaged in a battle to receive royalties for performances of his music by synthesizers in elevators, is also very eccentric.

The cast includes 15 characters. The character of Petr's pedophile boss is sometimes omitted.
