Captured in the heart of Palombia by Chahuta Indians and sold to exotic animal traffickers, a marsupilami lands in the port of Antwerp in the 1950s. Managing to escape, he arrives in the suburbs of Brussels and is taken in by François, a young boy who is a fan of animals and whose daily life is far from easy. François is picked on by the local kids, particularly because his father had been a German soldier, an unforgivable crime in those postwar years; a fact he and his mother cannot escape. Both are ostracized for their connection to past events.
