Noé, overwhelmed by loss and heartbreak, sets out on the Camino de Santiago from Jaca when he discovers an old notebook written thirty-five years earlier. In it, Gabriel reveals that his wife, Vega, is pregnant, but she suffers from terminal cancer. Both start the route to Santiago de Compostela with a purpose. The shocking content of the notebook leads Noé to turn the search for the couple into his particular grail, into a pagan way of the cross and a game in which he bets his life along the Camino.
