In this animated short, a terrible curse deprives Balthasar's kingdom of its stories. Taking the unicorn's horn back into The Belly of the Earth is the solution. Poppety will lead an expedition, by chance uncovering a hitherto closely guarded family secret. Poppety in the Fall concludes the thrilling animated series of 4 seasons in the life of Léon, the adopted bear cub.

Sebastian, a young man, has decided to follow instructions intended for someone else, without knowing where they will take him. Something else he does not know is that Gerard Dorez, a cop on a knife-edge, is tailing him. When he reaches his destination, Sebastian falls into a degenerate, clandestine world of mental chaos behind closed doors in which men gamble on the lives of others men.
