It's very long and it literally just documents the life cycle of pigs in Australia. Iirc there's no narration or anything. So it's just long shots of pigs living in hell. It's incredibly monotonous, but in a way that crushes the soul, because we're watching just a tiny fragment of what these pigs have to go through every day of their life until their slaughter. Banality of evil, but you can feel it seep into your skin
