In charge of protecting a 5-year-old orphan girl wanted by the police, inspector Wen meets Ms. Li, the director of an uncommon orphanage. A place that houses children whose parents have been sentenced to death: disgraced children casted aside by the society.
She agrees to hide little Wang Hua and in return, makes the police officer promise to investigate the recent and worrying disappearances of eleven of her protégés. Gradually found dead across the streets of Beijing, many of them are showing traces of Crystal in their blood.
This “happiness drug” causes devastating side effects that turn those who consume it into human bombs. Little present in China, it seems to be slowly spreading around the country via a network in whichmany children seem to find themselves drawn in.
During his investigation, Inspector Wen will discover that a strange link unites the orphanage with this criminal organization. But it is when little Wang Hua also disappears that the investigation takes on a whole new dimension for the police officer.
What dark secret hides behind the disappearances of the eleven children? And most of all behind the little 5-year-old’s disappearance?
