Blueback

While researching Australia's deteriorating coral reefs, marine biologist Abby (Mia Wasikowska) receives word of her activist mother Dora's (Radha Mitchell) stroke. As she rushes to her seaside hometown to care for Dora, Abby recalls her childhood years spent living in harmony with the ocean, and her mother's efforts to protect the bay from greedy developers and invasive fishermen alike, often to the detriment of their own relationship.

Among the coral gardens, Abby befriends a rare fish, the blue groper — affectionately named Blueback — a tether to her environmentalism, and the key to reminding Abby and Dora of their love for each another and the vulnerable waters they call home.

Based on Tim Winton's 1997 novella of the same name.
