There are a few dysfunctional inhabitants in a demolished old building. Life has been hard for Fat Chou (Lam Suet) and crippled Ah Fung, but they lived harmoniously. As Ah Fung realises that she can no longer satisfy Fat Chau, she allows him to have sex with prostitutes, but not with the same one all the time. Soon, Fat Chou falls in love with one of the prostitutes, Kil-Kil and therefore, breaks his promise. The tenants later find their lives taking a major turn.
