The odd fisherman Onno lives on a tiny little island in the Wadden Sea and prefers to be all alone - until one day a little otter runs up to him: Ontje. Against all odds, the two become inseparable friends who experience adventures about friendship, jealousy and security together.
Unfortunately the movie Onno und Ontje is not yet available on HBO Max.
