4k quality, ultra-high definition and realistic, the world of the sand planet "Dune". A large river is brown and murky with sand. A young man is riding his motorcycle along the winding sandy road that runs alongside the river. He drives his motorcycle at full speed toward the upstream of the river. Dust rises behind the motorcycle. The sky is dim and cloudy, and the shadows are deep. The young man is wearing black leather pants and off-road boots. The camera provides a bird's-eye view of the whole scene from above. He is in a hurry about something.
