Dan Geraldo, a reporter who needs a scoop, arrives in Chiquito, Palombia, but he does not think that he is going to discover anything significant, other than an interview with the Paya; the indigenous tribes of Palombia. However, accompanied by the eccentric and poor vet and tour guide, Pablito, whose children dislike him and deem him a liar, Dan is told the myth of the Marsupilami, a mythical and extremely rare creature that is believed to inhabit the Palombian rainforest and to be a real species.
