Monroe is called to deal with a complaint against an officer from Stafford Row, where the victim has accused him of offering acquittal in return for sex. Meanwhile, Brownlow attends a charity dinner held by the Sun Hill Businessman's Association. When the daughter of a very prominent community figure disappears, Brownlow urges CID to make it their top priority. Meanwhile, Monroe's suspect is brought in by McCann and Hagen for harassment. When the suspect reveals information to the woman's disappearance, Monroe realises that the two events are connected - which subsequently leads him into conflict within the Chinese community, as well as a murky world of drugs, vice, corruption and violence.
