An unidentified young European man is found on a Chinese countryside riverbank, naked, and seemingly unable (or unwilling) to communicate. He is taken to a hospital, where no physical reason for his silence is found, and it is decided to send him to a mental asylum. Jiang, n orderly at the hospital, senses that the patient isn't crazy but just troubled, and takes off with the young man, hoping to get him to open up about his past. One clue comes when Jiang spots him calling a young Chinese woman on his cell phone, just to hear her voice. Looking into their relationship, Jiang eventually discovers the devastating event that apparently caused him to withdraw from life.
This 2012 feature is an excellent suspense-filled story, with capable acting and direction, definitely worth a look. Has been featured at several international film festivals. DVD dialogue is in Mandarin with English subtitles, with extras including an interview with director Simon Chung. Not rated, but would be a solid R for nudity and simulated sexual activity. Four stars out of five.
