Lin Wanqing, a 1940s spy, accidentally travels to the present during a mission. Waking up as her 22-year-old self, she’s shocked to meet her 80-year-old son who calls her "great-grandma"—it turns out she’s been missing for 80 years. Her late husband left a mysterious key, hiding both an unfinished mission and a century-old love. As she navigates modern life as a "reverse-aged" woman (and gets into silly trouble), she teams up with her "elderly son" to crack the key, determined to find her husband and keep their 80-year-overdue reunion promise.
