And what if Man were descended from the clown...

On the roof of a building, around a huge billboard, three remarkable characters meet: Barbouillette, a "Sonne­ Heure" by trade - in fact a most peculiar "bell ringer" - who actually lives in the billboard, Monsieur, a tragic actor who has never but never learned to laugh, and Bulle, an athletic and optimistic "contr-actor" there to repair the billboard. The shock (7.4 on the Richter scale!) resulting from the meeting of these three strange characters leads to a quite exhaustive portrait, clownish and musical, with many emotions and jokes getting the action moving again.
