Soda Master plunges into the lives of three middle-aged men, once inseparable friends who bonded over making kungfu movies in their 1988 middle school film club. Now 51 and feeling stagnant, their past collides with the present when human bones are discovered at a construction site in their childhood town. One friend, disturbed by the news, reunites with the others after 37 years. Amidst rekindling old memories, they discover an unsettling blank in their recollection of their cherished movie club advisor. This mystery deepens with the unearthing of a club photo, ominously marked "missing." Compelled by a newfound purpose, the trio embarks on a compelling investigation to unravel the puzzling disappearance of their advisor, hoping to find answers to a decades-old enigma.
