The video shows a person underwater, holding a large plastic bag. The person is moving the bag around, possibly to catch something or to look inside it. The water is clear, and the person's movements are slow and deliberate. The plastic bag appears to be filled with air, making it buoyant. The person's hands are visible, and they seem to be wearing a wetsuit. The background is blurred, but it appears to be a natural body of water, possibly a lake or a river.
