The video shows a close-up of a body of water, possibly a river or stream, with a fish swimming in it. The water is moving rapidly, creating white foam as it flows. The fish is dark in color and appears to be struggling to swim against the current. The video is shot from a low angle, looking up at the water, and the fish is the only visible living creature in the frame. The water is clear, and the fish is the only object in motion.
