Part 4/9:
In the classroom, their father and Biology teacher, Michael, attempts to educate students about parasites, projecting a sense of normalcy against a backdrop of escalating fear as more cases of the worm flu surface. Unfortunately, normality begins to unravel as Gracie's condition worsens, and the sisters bear witness to the escalating severity of the epidemic firsthand.
Classes are hastily canceled after Gracie’s seizure, and chaos soon ensues as military personnel envelop the small town, enforcing isolation measures. Emma’s concern grows as she watches her community spiral out of control, driven by government proclamations and eerie news reports about the parasite's aggressive nature.
