Ága is a film that tells the story of Nanook and Sedna, who live in a yurt on the snow-covered fields of the North, following the traditions of their ancestors. They appear to be the last people on Earth, living alone in the wilderness.
However, their traditional lifestyle begins to change slowly but inevitably. Hunting becomes more difficult, animals die from unexplained causes, and the ice melts earlier each year.
Chena, their only connection to the outside world, visits them regularly. Their daughter Ága left the icy tundra long ago due to a family feud.
When Sedna's health deteriorates, Nanook decides to fulfill her wish. He embarks on a long journey to find Ága.
