Just days after Raynor learns that Moth, her husband of 32 years, is terminally ill, their home and livelihood is taken away. With nothing left and little time, they make the brave and impulsive decision to walk the 630 miles of the sea-swept South West Coast Path, from Somerset to Dorset, via Devon and Cornwall. They have almost no money for food or shelter and must carry only the essentials for survival on their backs as they live wild in the ancient, weathered landscape of cliffs, sea and sky. Yet through every step, every encounter, and every test along the way, their walk becomes a remarkable journey.
