This is the Sex and the City called "Sodom". Although everyone is well-dressed during the day, at night it is a hotbed of violence, prostitution and drugs. The four major families that dominate the night in this place are Rong, Lian, Mei and Zhu. Although on the surface the four major families check and balance each other and live in peace, privately the fighting has never stopped. The story revolves around the love-hate entanglements and battles of wits and courage between the current heads of four major families.
