Seeking South follows trail runner Keisuke Minami as he takes on the fastest-known-time (FKT) challenge of the Grand Randonée 10 (GR10)—a grueling 914 km journey across the Pyrenees in southern France, from the Atlantic to the Mediterranean. The route typically takes 45-60 days to complete, but Minami sets out to finish in just over 9 days. Why would someone willingly endure pain, isolation, and total exhaustion? What might keep him running? Minami, whose name means “south” in Japanese, runs across the mountains as the film pursues the story behind his relentless drive. A story of obsession, resilience, and the demons that push us forward, Seeking South is an intimate look at the mind of an endurance athlete and the weight of the past he runs to escape—or embrace.
