As Shanghai surpasses Hong Kong as Asia's most important city, Zhong Fong's Office of Special Investigations faces an increasingly sophisticated, and increasingly global, breed of criminal.
When Zong follows a disturbing lead, he finds himself in a sleepy rural province. Here, he is shocked to discover a blood-trafficking racket and a massive outbreak of AIDS. In pursuit of the organisation behind the trafficking, he embarks on what proves to be the longest journey of his life. It will eventually take him to the streets of Vancouver - and to a meeting with a man who holds an old, and potentially lethal, grudge.
