Hong Kong, twenty years later. The city is a perpetual construction site where the wheel of development must turn to build more shopping malls and higher residential towers. Enter members of the all-girl pop sensation, Heartbeat 48, an ever-expanding army of eco-warriors who are tasked with checking the heartbeats of centuries-old trees and villages and losing no time to pronounce their deaths. When Doy, an internet nerd and one of the few surviving village natives, is transported from the past into the fanciful realm of cute tutu outfits dresses, toy stethoscopes and hugging farewell routines – all staged for the benefit of the camera – he gets trapped a nightmare he can’t wake up from.

Shawn Yue and Miriam Yeung reprise their popular roles as a star-crossed couple who strive to stay together happily ever after, only to find their already precarious relationship further strained, when Jimmy’s childhood friend asks him to donate sperm, and Cherie is troubled by the re-marriage of her father.
