In the remote town of Camellia, residents "disappeared out of thin air" one after another, leaving only a strange white camellia at the scene. Foreign reporter Shen Liang conducted an in-depth investigation to find the truth, but found that all the missing persons were related to an unjust case ten years ago. When the dusty crime was uncovered, he realized that the "murderer" who carried out the trial in the name of Camellia might be hidden among the seemingly simple townspeople. Everyone is a suspect, and everyone may be the next person to disappear.
