In 2147, Lao Ma, an Earth deliveryman who faithfully follows the interstellar courier regulations, encounters a mysterious object falling in a flash of blue light while making a late-night delivery. He discovers an alien girl named Arian, who is hiding a secret. He knows that contact with extraterrestrial life will get his memory erased, but his soft heart leads him to break the rules and hide her in his delivery van. Meanwhile, an interstellar pursuit team is due to arrive in 24 hours. Caught between strict interstellar laws and a deadly manhunt on one side, and the girl’s mysterious origins and inner resolve on the other, Lao Ma is forced onto a perilous interstellar escort mission. The fate of an ordinary man is now inextricably bound to the stars.
