This is the story of a young giant otter's journey to adulthood. Rescued by local fishermen as a baby and raised by giant otter expert Carolina Vargas, this is the story of a young giant otter's journey to adulthood. At first, Sancho is utterly dependent on Carolina, and has to be bottle fed and taught how to catch fish. Eventually Carolina knows that she will have to break their extraordinary bond as Sancho makes his way back into the wild. Giant otters are highly social animals, so Carolina doesn't know whether an orphaned giant otter can survive alone in the world's biggest wetland. In the idyllic Pantanal, we follow Sancho's story as he learns to survive in a world fraught with danger.

Natural World is a nature documentary television series broadcast annually on BBC Two and regarded by the BBC as its flagship natural history brand. It is currently the longest-running series in its genre on British television, with more than 400 episodes broadcast since its inception in 1983. Natural World is produced by the BBC Natural History Unit in Bristol, but individual programmes can be in-house productions, collaborative productions with other broadcasters or films made and distributed by independent production companies and purchased by the BBC. Natural World programmes are often broadcast as PBS Nature episodes in the USA. Since 2008, most Natural World programmes have been shot and broadcast in high definition.
