Zu is newly sober when she receives news that she is to become the sole guardian of her half-sister named Music, a young girl on the autism spectrum. The film explores two of Sia's favorite themes: finding your voice and creating family.

Critic Reviews:

• " For friends and family members of those on the spectrum, it's … an acknowledgment that people with autism can be remarkable without having remarkable abilities. " – Tara Brady(Irish Times)

• " Despite the film's controversy, the film is a beautiful piece of art, and a great accomplishment for a first time director." – Alex Clement (HeyUGuys)

• " Yes, we want ASD actors cast in parts drawn from their life experiences, but we cannot deny that Music considers those experiences with heart, integrity and artistry regardless. " – Simon Foster (Screen-Space)
