When rookie investigator, Apo Nattawin, receives multiple invitations leading him to the locations of murders, he tries to use them to catch a serial killer known as 'Crane'. However, this is easier said than done. No matter what he tries, Crane is always a step ahead of him and Apo is getting closer and closer to the point of giving up. However, when a university professor, Mile Phakphum, begins to interfere in Apo's investigations, Apo finds a new way to read the invitations. With Mile's help, Apo finds himself looking at things differently, bringing him closer to the answer he's been trying to look for this whole time.
