Mooncakes tells the story of a young girl celebrating the Chinese Moon Festival with her parents. As they eat mooncakes, drink tea, and gaze at the night sky, the girl's parents tell her ancient tales about figures from Chinese mythology who are said to live on the moon, including Chang-E, a woman who drank an elixir of immortality and fled to the moon; Wu-Gang, an eternal woodcutter still chopping at an uncuttable tree; and Jade Rabbit, who offered himself to be eaten by poor travelers.
