Retired school principal, Pak Tsin Ngam, has somehow returned to Hong Kong from Canada. He goes to the familiar location of Lower Ngau Tau Kok Estate, which has been redeveloped, to look for certain sopranos whose voices keep resonating in his head. His granddaughter, the reclusive illustrator Xuet, promises to help him find his former students from the elementary school choir from forty years ago. The divorced Xuet, with the help of her investigator friend and "fake husband" Luk Gu Nam, and former students Dai Zhan Liang and Dai Gan Jing Yi, finally finds the other members & their former music teacher and reunites the choir. But these middle-aged men, who have experienced life's hardships, have become like oily fried sticks who have lost hope in life. In the process of searching for the soprano, Xuet and Gu Nam develop a subtle relationship while the middle-aged men rediscover their passion for life and shine on the stage once again!
