Present Day. Paris. Laura Siprien (Monica Bellucci) leads the perfect life with her single son, Liu-San (Nicolas Thau), a Mongolian orphan whom she lovingly adopted seven years ago. Laura is able to give her child a good home due to her high-level career as an embassy translator . But being a single mother isn’t always easy, sometimes she needs some support; Laura is luckily able to find such via her good friend and “adopted” mother, Sybille Weber (Catherine Deneuve). Sybille is the executive director of the Inyt Foundation, an organization financing scientific research. Recently, Laura discovers that she and and her young son are having the same weird dreams at the same time. Night after night these occurrences are taking place. Things become even stranger when Liu-San seems to fall victim of invisible forces: speaking in a foreign language in his sleep, and a strange round mark appears on his chest. Briefly, Laura is reassured by Dr. Vonkel (Peter Bonke), a close friend who has known Liu-San since his adoption from Mongolia. Suddenly, Dr. Vonkel is discovered murdered; this event combined with her son’s behavior causes Laura to spiral slowly into madness. She hallucinates she's being attacked by wild animals. She feels more and more distressed and alone because no one believes her about what is happening to her and her son. Except Serguei Makov (Moritz Bleibtreu). Serguei is a Russian counselor recently working in the same embassy as Laura. He has a soft spot for her and would do anything to help her figure out what is happening. When investigators helping Laura are murdered, things become more arcane: Liu-San is kidnapped. Her obsession now is to find her son and bring him home. On the trail of her abducted child, she begins to figure out that she is the victim of a supernatural conspiracy, covered-up by the Inyt Foundation. The people closest to her have betrayed her, even Sybille. Laura learns that the conspirators’ plan is to sacrifice Liu-San in order to gain the eternal life. To save her son from a gruesome death, Laura travels to Mongolia, where everything involving this conspiracy seems to be centered. With the magic help of the “Tsevens”, nomads living in the Mongolian forest, she finds Liu-San and finds the power within her to stop the evil forces bent on taking her son.
