Ployjued's bland life takes a sudden turn when Phupha, a top senior she has a crush on, invites her to join him on his dangerous mission to expose the Chantharusati Family, a strange cult gaining followers throughout their province.

Worse, "Father," the cult's prophet, seems to take a special interest in her—to a life-threatening degree.
