The Whanganui River is the first river in the world to be recognised as a legal person, as a living adult indivisible being. Maori river guardian Ned Tapa invites a First Nations Elder from Australia and his daughter, who are activists to saving their own dying river back home, on a five-day canoe trip down this sacred river. Together, this diverse group of people embraces the spirit of the river and tries to find what is needed to save the planet.
