On an isolated island called Peach Blossom Paradise lives a group of sorcerers who never age or die. But immortality has also robbed them of many ordinary joys: they have lost their sense of taste and cannot have children. Though outwardly optimistic, inside they are as lifeless as still water. Until one day, the sorcerer Bai Ze takes a job helping someone summon a soul. Along the way, he meets Gu Ming, a trainee policewoman searching for a missing mother and child. As the two gradually delve deeper into the case, a shocking conspiracy begins to unfold.
