From the lagoons of Mexico to Arctic glaciers, grey whale mothers are swimming with their calves, past predatory orcas, through a warming sea. For ten thousand miles, they endure one of the longest mammalian migrations on the planet.
Following them, by bus, train and ferry, are Doreen Cunningham and her young son Max, in pursuit of a wild hope: that their family of two can make it by themselves.
Doreen first visited Utqiagvik, the northernmost town in Alaska, as a young journalist reporting on climate change among indigenous whaling communities.
Years later, plunged into sudden poverty and isolation, living in a Women’s Refuge with her baby son, Doreen embarks on an extraordinary adventure: taking Max to follow the grey whale migration all the way north to the Inupiaq family that took her in.
