They are unique animals. On the beaches of the Bissagos Islands, off the coast of Guinea Bissau, in the Atlantic, we can find strange footprints. They seem to be misplaced since they are made by the hippopotamus, an animal that otherwise lives in fresh water. But these are different ones. This is a population of hippos that lives in coastal waters and is the most western one in the range of this species. This film explores the life within this hippo colony. We will get to know their environment and the animals whith whom they share this little known place in West Africa.
