Plot summary

In the New Territories, the Luk clan has held rural land for more than a century under a small house policy that lets indigenous male villagers apply to build a three-story house free of land premium. When the government decides to stop taking applications, developers move to consolidate the remaining rights, and Uncle To, the clan's head, means to take the whole project for himself. Landowner Yuen holds the deciding vote over hundreds of acres of ancestral farmland. Yuen dies in a staged car crash, and To's chauffeur Law Wing-jau is jailed for it. Released five years later, Wing-jau finds the Luk family grown into the territory's largest property empire, and Joe, a computer whiz he met inside, plants spyware in the phones of Luk Kam-keung and the other villagers under To.
