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.—KGF Vissers
