It’s been a year after the events from the previous movie. Shih-Nan (Carol Cheng) and always accompanying her Sheng (Alfred Cheung) were rewarded by the PRC authorities and allowed to settle in Hong Kong for good. Shih-Nan, now not so devoted to the ideology of the communist party, decides to become a real Hongker and assume the capitalist way of life. However, things get complicated when she befriends a recently acquainted neighbour from upstairs. Soon afterwards, the fearless Inspector has to act again in the name of law enforcement when it turns out that her cousin is kidnapped in HK.
