Based on the profound true story, husband and wife Raynor and Moth Winn (Jason Issacs and Gillian Anderson) embark on a 630-mile trek after being forcibly removed from their home. Hoping that in nature they will find solace and a sense of acceptance, they walk through the beautiful but rugged coastline of South West England – a journey that is exhilarating, challenging, and liberating in equal measures.
