Fong Fong (Cecilia Cheung) is a shopaholic who can't control her shopping fanaticism, which leaves her unemployed and in debt. Desperate for help, Fong Fong seeks help from a psychologist, Gan Yan (Lau Ching Wan). With Gan Yan’s help, Fong Fong slowly improves. Meanwhile, Fong Fong bumps into Kong Fu (Jordan Chan), a weird millionaire who is very calculative when it comes to spending money, but also a shopaholic. Fong Fong thinks that the reason behind Kong Fu's thriftiness is that he is following in her footsteps. When Kong Fu refuses to see the psychologist, thinking it is a waste of money, Fong Fong pities him and teaches him to save money. Will Fong Fong get over her shopaholic condition? Who will Fong Fong chose; a thrifty millionaire or a kind-hearted eccentric doctor?
