Over the Moon is a retelling of a classic Chinese myth. When Fei Fei (Cathy Ang) was a young girl, her mother told her the story of Chang’e, the moon goddess of Chinese mythology. Now, the 13-year-old wants to visit the goddess on the moon to prove it's not just a silly myth. Being a STEM-proficient student, she builds a rocket ship herself and sets out on her journey.
