Aliens of the Amazon

That smelly, pale yellow liquid that people flush down the toilet every day is an industrial fertilizer, a diagnostic tool, a medicine, a renewable energy resource; it is an inexhaustible substance that is produced daily in huge quantities. This is the golden story of urine.

It was long believed that animals only played to learn, only mated to reproduce and only took drugs by accident. But sometimes, they just do it for fun! Research has revealed that animals seek for pleasure just like humans do, and that there are many ways in which they enjoy themselves. Did you know that rats loved to play hide-and-seek? That primates played erotic games to ease tensions within their groups? Or that reindeers were quite fond of hallucinogenic mushrooms? Scientists show that this quest for pleasure – as wild as it can get – might even be a key of evolution and biodiversity! Combining the testimonies of international ethologists, scientific archives and sequences showing the animals in their natural habitats, this unusual documentary reveals the complexity of animal pleasure.
