While David Stark is asked to open a law office in Beijing, his lover, detective Liu Hulan, receives an urgent message from an old friend imploring her to investigate the suspicious death of her daughter, who worked for a toy company about to be sold to David's new client, Tartan Enterprises. Despite David's protests, Hulan goes undercover at the toy factory in the rural village of Da Shui, deep in the heart of China. It is a place that forces Hulan to face a past she has long been running from. Once there, rather than finding answers to the girl's death, Hulan unearths more questions, all of which point to possible crimes committed by David's client. Suddenly Hulan and David find themselves on opposing sides: One of them is trying to expose a company and unearth a killer, while the other is ethically bound to protect his client. As pressures mount and danger increases, Hulan and David uncover universal truths about good and evil, right and wrong-and the sometimes subtle lines that distinguish them.
