Amy's (Alana De Roma) father, Will Enker (Nick Barker), was a popular rock musician accidentally electrocuted while performing on stage. The psychological trauma leaves Amy mute and deaf. At the age of eight she is brought by her mother, Tanya (Rachel Griffiths), to Melbourne to diagnose the reasons for her continued silence. Amy befriends her neighbor, Robert (Ben Mendelsohn), and while social workers try desperately to get her to speak and go to school, she makes the choice to communicate again and begins to sing along to Robert's rock songs after three years of silence. Her mother works out her own emotional issues with the help of a therapist.
