In a forgotten corner of a lonely town, a mysterious letter slips through the mail slot of a long-abandoned general store, sparking an extraordinary connection across time. Based on the novel by Keigo Higashino and directed by Jie Han, this heartfelt drama weaves together the lives of three troubled youths in 2017—played by Karry Wang, Dilraba Dilmurat, and Zijian Dong—with the residents of 1993, who seek guidance by writing letters to the store's enigmatic former proprietor, known as Namiya. As the modern-day trio, each grappling with their own personal crises, begins responding to these decades-old pleas for help, they find their own lives profoundly changed by the wisdom and hope they dispense. With a moving performance from Jackie Chan as the store's original owner, the film explores how simple acts of kindness can ripple through time, creating a poignant and magical tapestry of interconnected fates where the past and present gently collide to heal wounded souls.
