Pressured by her abusive, alcoholic father (Wong Chi-keung) to become a hostess, Chu (Maggie Cheung Man-yuk) reluctantly agrees and is assigned by her unit’s mamasan (Hu Chin) to share an apartment with veteran B-girls Gigi (Cherie Chung Cho-hung) and Porsche (Carol Cheng Yu-ling). Gigi works hard in order to raise money and get her husband out of jail, while the aging Porsche finds that clients are no longer as receptive to her as they once were. Gigi is notorious for "cheating" her customers (eg ducking out of sleeping with them) and, when she and Chu pull this act with Tsimshatsui triad bosses Chuen (Shing Fui-on) and Mark (Stephen Chan Tak-kwong), the men plot to take revenge. Meanwhile, Chu sells her virginity to a European client for HK$30,000, money her father eagerly pockets in order to pay his loan shark. Unfortunately for her, the trick turns out to be a far from ideal or gentle lover. Desperate to liberate her suffering hubby, Gigi pleads with a bigshot lawyer to take the case. However, since she does not have enough money to pay his fee, Gigi must agree to his demands for other services. While trying to secure a loan so that she can travel to America and see her daughter, Porsche sets Chu up with her banker and the naive girl soon falls in love. Porsche's old flame offers to whisk her away to America and she is ecstatic but is he still the Chow Yun-fat lookalike she remembers?

Like the majority of triad "hero" pictures from this period, hostess movies tend to be rigid in their construction and MOON, STAR & SUN is no different. Unfortunately, it compounds this sub-genre's inherent weaknesses by committing its worst mistake: making all of the men stereotypical pigs. In the better hostess pictures, such as BET ON FIRE (reviewed in issue #204), the exaggerated characters are used predominantly for comedic asides or to add additional color. The complete lack of dimension and sincerity in the lead males here just makes the already melodramatic situations even harder to swallow. The idea, of course, is to show that the three women go through hell dealing with the lowlife customers every night on the job, only to be betrayed by the men that they truly trust. Trouble is, the viewer just does not buy that these ladies (especially Porsche and Gigi, who have been around the block more than a few times) would allow themselves to be so manipulated and emotionally abused by men just as transparently shallow as their clients. Michael Mak Dong-kit (SEX AND ZEN) realizes that the storyline lacks subtlety and affords it none in his direction, and this negatively impacts the performances as well. Mak Brothers regulars Ng Hong-ning and Elvis Tsui Kam-kong appear briefly.
