Compulsive disorders plague Hong Kong: Fong Fong Fong, a foundling who’s now a nurse, is a shopaholic who seeks psychiatric help from Kan Yan (Choosey) Lee, who’s frozen by an inability to choose. Into the mix come Kung Fu (Richie) Ho, a wealthy man who is stingy but also will buy anything someone else wants, and Ding Dong Ding, Lee’s binge-eating bargain-shopping ex-girlfriend who reappears in hopes Lee will now choose her. Both men propose to both women who say yes to both. Family and friends are inept at helping to sort it out, and even if the four get the wedding vows straight, will anyone be cured? Does Hong Kong need more than a Prozac?
