The hypnotically beautiful Shu Qi (the main reason I was drawn to this film) plays police detective Ha, who is assigned to a case of rape-and-murder that occurred in a local forest. A lot of people have committed suicide in the same forest lately (some traveling a long distance for that purpose), and the place is considered by many to be haunted. Detective Ha asks for the help of a botanist (Ekin Cheng), who has developed a device that can receive "messages" from plants and trees, drawing him away from his girlfriend (Rain Li), a successful TV reporter who regularly interviews people who have had "near death experiences" in the same forest. The script tries to combine two different main story lines (one involving Shu Qi's investigation and Ekin Cheng's efforts to use the trees as "witnesses", the other involving the suicides and disappearances in the forest and what is causing them), and ultimately comes across a bit muddled. The film has some striking images and riveting scenes, but the resolution is not fully satisfying. Shu Qi's and Ekin Cheng's characters don't have much depth: all we really learn about them is that they are consumed by their jobs and determined to do them right. Rain Li not only gives Shu Qi some serious competition in the looks department, but also creates what is easily the most human and sympathetic character in the film. (**1/2)
