The Interior brings back the duo of Chinese police detective Liu Hulan and her lover, American attorney David Stark. This time, for Hulan, the case is alarmingly personal, unearthing her own buried past and a stunning network of violence and conspiracy. When an old friend from a village deep within China's interior asks Hulan to find out the truth about her daughter's suspicious suicide, Hulan cannot refuse -- even if it means going undercover in a newly built American toy factory linked to David's firm and finding her way into the heart of a dangerous mystery. Meanwhile, David's new job has him trapped in a tangle of legal and ethical dilemmas. To extricate himself, he must first decide whom to trust and where his greatest duty lies.
