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.
