Moon Rider is a coming-of-age story about the bike rider Rasmus Quaade. The film follows young Rasmus' struggle to become a professional rider, a rough and winding road through hell and back. Shot on fragile Super8 and raw helmet-cam, it is a journey seen from the inside of a young man's head - it is a personal story entrusted to the spectator by Rasmus himself from his intimate diary.
