A bicycle race is held every year in a pass of the Alps called Parpaillon. With the energy of a skillful cyclist perhaps as a great tribute to François, the mailman played by Tati in The Big Day, Moullet makes a comedy by pedaling at a pace that allows him to reinvent the possibilities of film gags. La Cabale des oursins is a guided tour to the northern France, transformed into a Geography lesson in the pataphysical style of an Alfred Jarry disciple.
