In a forest on the outskirts of Barcelona an old shepherd and his flock live alongside a high-tech laboratory for animal experimentation. Two opposite worlds facing each other. Two worlds that are two sides of the same coin. While the shepherd, afflicted with a bone disease, witnesses his profession disappearing, scientists are busier than ever researching the covid vaccine. 'Fauna' is a science fiction fable about the relationship between humans, animals and science in post-pandemic times.
