"Everything in me said I had to do it." Martin de Vries decides, without any preparation worth mentioning, to walk the Camino, the famous pilgrims’ way to Santiago de Compostela. From Le Puy-en-Velay in central France to north-west Spain; a journey of 1,600 kilometres, taking almost 70 days. He films himself while walking – his feet, his shadow, the path, the fields and woods – and tries to get to the bottom of why he set out on this adventure.
