'While marine biologist Abby (Mia Wasikowska) is out on a boat examining the slow destruction of coral reefs, she’s called back home with the news that her mother has had a debilitating stroke, which has left her unable to speak. Abby begins reflecting on her childhood and the immense influence her mother, Dora (Radha Mitchell), had on her worldview. Through flashbacks, we meet the teenage Abby, played by newcomer Ilsa Fogg, who captures confidence and curiosity, taking a deep interest in protecting the bay where they live. In between amusing encounters with a local fisherman (Eric Bana), she maintains a bond with a groper fish affectionately named Blueback, who becomes a reminder of all the wonders the ocean has to offer and a path to healing a rift between Abby and her mother.'
