When a frantic man darts in front of their bus on a desolate Armenian road, Dr. Miller and his students decide to take the man to an old village for assistance.
After straying too close to the old man imprisoned in the pit, Rick goes missing, while Cameron wakes up in the pit itself.
With the char voki released from its constraints from inside the body of the prisoner, the entire village falls under severe threat.
The char voki's cunningly lethal discretion cleaves division inside the group of students, as well as within the village of protectors.
As betrayal threatens to undermine the village's sacred duty, the mark that is burned onto Karen's neck is discovered in an ancient text.
After returning from the portal, Karen reveals that the char voki is not the only entity at work, and their goal is humanity's extinction.
