Most documentaries about animals tell you have they live and reproduce. In this one by the great Bert Haantsra you witness a kind of soap-episode. He gives names to the monkeys and he follows them for a long period. Although the chimps live in a zoo, you get a great inside look on how these animals behave and interact with each other. The climax of the film is when Haanstra places a fake lion to see how the chimps react.
