Can the Czech Republic leave a lasting mark on EXPO 2020 and create a project that will help the world? Such an attempt was made in 2020 in Dubai by a team led by Jiří František Potužník. The documentary of Karel Žalud follows Potužník’s difficult journey along with seven other creators of an invention that can create oases by extracting water from the air. This documentary reflects on the events surrounding EXPO 2020 and the broader context of current water shortages, which is not just an issue in arid desert areas.
