The video shows a scuba diver underwater, surrounded by a large school of fish. The diver is wearing a black wetsuit and is holding a camera in his hands. The water is a deep blue color, and the fish are swimming around the diver in a circular pattern. The diver is moving slowly through the water, and the fish are following him closely. The light from the diver's flashlight illuminates the scene, casting a bright spot on the fish and the surrounding water.
