A documentary that follows a couple looking after their severely disabled daughter who was declared "near" to being brain dead at birth poses important questions to audiences about how they understand life and the meaning of existence.

The parents of Honoka Nishimura, now 14, were told by doctors that she would never exhibit consciousness when she was born in 2007. Told she would continue to require medical attention around the clock, the couple brought her back to their home in Saitama when she was 9 months old.

"Honoka" follows the girl, age 3, and her parents over three years. Like any parents, the Nishimuras shower her with affection, taking her on outings and reading picture books in her presence, while her mother, Risa, 45, also takes charge of her medical care.
