Mei runs her own private investigation business, although she calls it an information consultancy because private investigation is illegal in China. When she is asked to find a missing girl, a popular singer called Kaili, she expects to find that the girl is just taking some time out. But Kaili is eventually found dead, apparently murdered, and Mei is warned off the case. Curious, Mei continues with the investigation, and finds a link with a student called Lin who was involved with the student uprising back in 1989. Can Mei find out what really happened to Kaili? And where is the mysterious Lin?
