My Octopus Teacher plot
Craig Foster swims every day in the icy seas of South Africa and at one point comes across a special companion: a young curious octopus. Foster's new octopus friend lives in a kelp forest, and there's a lot more to explore there than he first thought possible. Slowly but surely, the two gain each other's trust and the curious young octopus reveals more and more of the secrets of the underwater world to him. That is special in itself, but Foster himself also notices that he is physically changing: he can cope much better with the cold and can also hold his breath longer.
