This documentary follows the philosophy of Dosan Ahn Changho, a man who transformed his era through action rather than words. Young filmmakers from Korea embark on a journey across the United States, tracing the Dosan Musical and Dosan Symphony Orchestra tours that celebrate his enduring legacy. Through music, interviews, and the landscapes Dosan once walked, they rediscover his ideals of integrity, diligence, and community in the language of today. Retracing the footsteps of a youth from a century ago, the film asks a timeless question to our generation — How should we live, here and now?
