Budget cuts and a small student body cause Jiu Pu Elementary to be threatened with closure. In an attempt to prove their value as an institution and keep their doors open, the school enters a choir competition with the hopes of winning. The school tends to children from the Bunun tribe, an indigenous group from Taiwan that is known for their musical ability. Despite being musically challenged, Mr. Fang, along with Ms. Huang, the newly hired substitute, take on the challenge of teaching the children to sing.
While attending choir practices, the school children struggle with their own responsibilities at home, as many play crucial roles in attending to and earning money for their families. As the competition nears closer, the children begin to enjoy singing and excitement builds around their performance. By coming back to their traditional roots with the help of tribe elders, will the children find their own voices?
