In a breathtaking journey spanning 800 kilometers across the rugged spine of the Pyrenees, elite ultrarunner Fernanda Maciel takes on the legendary GR11 trail—alone. From the Atlantic shores of Hondarribia to the Mediterranean cliffs of Cap de Creus, she runs for twelve days and twelve hours, fully self-supported, carrying everything she needs to survive. But this is more than a test of endurance. Without crew, comfort, or contact, Fernanda ventures into profound solitude, where silence becomes a companion and the mountain a mirror. Each step becomes a meditation. Each moment, a confrontation with fear, fatigue—and herself. This stunning documentary invites you to witness the raw beauty of the land, the resilience of the human spirit, and the quiet power of being truly present.
