Arnold has been participating in this unconventional swimming contest for 23 years, and every year he constructs as fanciful as possible boats and floats.

As always, the entire family supports his ideas. Bożena - the wife and two adult daughters - Dagna and Marika - help him in building the new swimming vehicle.

From the beginning, their construction plans are failing apart… Moreover, Arnold decides to end his career and take part in the competition for the last time.

He hopes that his family will be able to stand on the podium and win for the last time.
