Hang in There, Kids! (2016)

Three kids grew up in a secluded indigenous tribe in the mountains and the woods. They are all very optimistic, energetic and playful, but they are also troubled by their own family issues. Their handicapped teacher opens an after-school session to help them with their schoolwork, and it's like a ray of love is shining on them. The teacher has a beautiful voice, but never sings. One day, the kids find a tape of their teacher's recording and are amazed by her voice. They decide to take this tape to Taipei.... What changes will this trip bring to all of their lives?
