In a forest, on the outskirts of Barcelona, an old shepherd and his flock live together with 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 -who is sick with a bone disease- sees how his profession disappears, the scientists are busier than ever researching the Covid vaccine. ‘Fauna’ is a reflection on the relationship between humans, animals and science in times of pandemic.
