On a weekend night in 2013, Sara (Yu Qiao), Jeana (Ho Pui Yu), and Papa (CK Kwok) gathered at Lan Kwai Fong, going in and out of the club. Jolie (Adam Hui), a foreign girl, has a partner like the United Nations, changing frequently, but she is unwilling to date seriously. The nightclub owner and cousin May dotes on her and often matches her with the nightclub manager Jacky (Pak Yu Chan). Although he already has a live-in girlfriend Jeana, their cohabitation relationship has developed to a pure living together, and their feelings are bland. Jacky has a good impression of Jolie because she looks like his ex-girlfriend. On the other hand, Jeana has always had a special liking for her best friend Sara's boyfriend Ashin (Alex Lam), and is jealous that Sara has found a good match with both inner and outer beauty. After learning that Sara and Ashin have made a rule of "each having their own sex and not interfering with each other", she has taken the opportunity to approach Ashin and show her affection. Papa is not good-looking, but she has a sense of smell. All her flaws can only be made up in the nightclub. Under the colorful lights, men all over the world will have vision problems after three cups. She will transform into a beautiful queen. Once, she and Parker (played by Ying Changyou), who has just joined the forensic department, had a mutual attraction. After waking up from a one-night stand, Papa disappeared at the boat party. Jolie suddenly walked dangerously on the top of the boat. Jacky rescued her. Sara has developed a relationship with Korean handsome man Kim (played by Lee Se-min), while Jeana seduces Ashin underwater; Papa sits alone in a corner during the day. Sara and Kim are having a hot affair. Kim leads Jolie and Sara out of Hong Kong and towards Korea. During the trip to Korea, Jolie was hospitalized after an accident at a nightclub. Jacky immediately flew to Korea to take care of her and was also clear about his feelings for her. Jolie not only did not accept him, but also returned to Hong Kong to escape.
