While visiting a village hospital sponsored by West Pacific Exports, Claire discovers that its malaria medicine is ineffective. As Sam tracks down those responsible for the drug tampering, Claire learns a harsh lesson in political realities.

When a newborn baby is left on the doorstep of the Cheng Detective Agency, Patricia and Sam try to figure out what they are to do with him. Patricia also receives a package containing Winston's fob watch, which was believed to be stolen when he was murdered. Meanwhile, Su Ling confronts her fear and desire over her relationship with Conrad, and Kang strikes a deal with the Devil.

Caught transporting explosives, Kang will face the gallows if Sam is unable to track down the truth about Lim Chee Kit, a leading trade unionist whose organization is suspected of being involved in a recent bombing. The case is further convoluted because Chee Kit's brother, James, is a well-connected businessman with political aspirations. Although he disagrees with Chee Kit's politics, James hires Sam and the agency to find and help his estranged brother before the police arrest him.
