Europe's most popular pilgrimage, the Camino de Santiago attracts wayfarers of all stripes to walk its ancient paths in search of meaning. One such pilgrim is Dane Johansen, an American cellist who ventured to walk the Camino with his instrument on his back, performing music for his fellow pilgrims along the way. Accompanied by the vast landscapes of Northern Spain, the haunting music of J.S. Bach for solo cello (performed by Johansen), and the very personal struggles and joys of the many pilgrims encountered along the way, 'Strangers on the Earth' examines the physical, mental and spiritual aspects of the concept of 'journey' and the vital role it can play as part of the human experience.
