The robot Tune embarks on a treacherous journey across the ocean floor in order to fulfill his mission. On his way through this alien environment, Tune meets Nara, a curious mermaid, who becomes his guide through this unfamiliar world. Tune comes to recognize the beauty and wonder within Nara's ocean home. Nara learns, perhaps too late, that her new robotic friend may mean to end her world as she knows it.
