The animated film "The Prince's voyage" (2019), based on a previous film "A Monkey's Tale" (1999), and inspired by Italo Calvino's book "The Baron in the Trees" (1957), is marked by a strong vegetal influence, diversity and continuity. The film invites us into a fictional world, in which monkeys are the main animal species, with contrasting lifestyles. Throughout the film, we encounter all kinds of plants: the plant that supports and accompanies life, or on the contrary, hinders constructions that destroy it; the wild or domesticated plant; the decorative plant; the pharmakon plant, both remedy and poison; the threatening plant, physical or chemical. The plant world is thus present in the wealth of transactions (Dewey and Bentley 1949) that are established between species. Anthropology tells us that nature does not exist, that it is the world from which humans have withdrawn, the baron does not withdraw from nature but looks "at the world from the top of his tree: everything, seen from there, was different". The way in which humans perceive continuities and discontinuities in the world between humans and non-humans (Descola, 2011) is expressed differently in the film according to the different ape peoples. Could we then invent and reinvent "nature"? We are invited, by following the baron and the film, to contemplate and question our link to plants. How do the transactions established with the living world make the world?
