Three Chinese teenagers sneak into a long-closed store one night to escape punishment for mischief they caused. They discover a 30-year-old letter addressed to the store's kindhearted owner (Jackie Chan), and have their lives changed when they write a response. Han Jie directed this fantasy drama, which is adapted from the best-selling novel by Japanese author Keigo Higashino. Karry Wang, Dilraba Dilmurat, Hao Lei, and Qin Hao co-star.
