First-time mother Aya can’t help noticing her daughter, Mu-chan, won’t say “Mama” or “Dada” like other kids―in fact, she shows little interest in communicating with her parents at all or in sitting still. When Aya finds out Mu-chan might be autistic, the idea of her child having a developmental delay shatters her vision of motherhood and leaves her spiraling in uncertainty. As the gap between Mu-chan and her peers widens, Aya and her husband must rally to support their daughter on her journey forward, hand in hand!
