Mees Kees in de Wolken (2019)

Popular elementary teacher ('Mees(ter') Kees enjoys starting up his class's time-line project and his birthday, except the present from his girlfriend (Marie) Louise: a balloon trip, but he's acrophobic. Furthermore, foppish principal Dreus demands everyone focuses on preparations for a 'classy celebration' for the school's upcoming 50th anniversary, which even requires ballroom dance lessons. Ultimately Kees gets all the balls in the air, with some help form his doting pupils.
