Milan's relationship with Dr. Eliška is developing promisingly, and when Milan finally decides to propose to her, it seems that nothing stands in the way of the wedding. Well, apart from one small "trifle" - Milan is still married to Slovakian woman Janka, Kryštof's mother, with whom he somehow forgot to divorce years ago! Apart from Milan's misgivings, there is another problem - the foursome's return to playing water polo is not going very well. There are only three left... and that's a hell of a lot... To save the group and pull his friend Jakub out of his depression, Kryštof decides to bring the aquabels to the pool with whom he wants to practice his performance. Honza is not too enthusiastic about Kryštof's plan at first, but later with the vision of rescuing a friend (and the possibility of being in the presence of beautiful aquabels) everyone starts preparing a performance called "Husband of the Hour".
