A grieving father makes a pilgrimage to the Pyrenees in honor of his late son, and experiences a major epiphany during his journey down the Way of Saint James. When his adult son (Emilio Estevez) is killed during an excursion down a Christian pilgrimage route, California doctor Tom (Martin Sheen) vows to complete the treacherous journey. As Tom sets down the 800 km path with only his son's guidebook and backpack, he forges powerful bonds with three fellow travelers (Yorick Van Wageningen, Deborah Kara Unger, James Nesbitt, who alter his perspective of the world and remind him what it means to lead a meaningful life.
