At the beginning of the 20th century, in a remote village in Patagonia, Argentina, an idealistic but disillusioned middle-aged Basque immigrant is challenged by his friends to undertake an epic adventure. Thus, he embarks on a journey that will test the limits of his will, risking his life to keep his word. This biopic is inspired by the real-life events of the incomparable Guillermo Larregui, known as El Vasco de la Carretilla.
