Eden believes that her younger brother Hyun-ho is suffering from 'electromagnetic hypersensitivity syndrome' and flees to escape electromagnetic waves. However, even in the mountains, Hyun-ho's condition does not improve.

Eden and Hyunho, brother and sister, have now lived in hiding in the mountains for three years to avoid all EMFs: electromagnetic frequencies. They reside deep in South Korea's last forest standing- the last EMF safe area. The two move ‘homes’ every day; they dig a burrow in the ground, set up an EMF shielding tent, and cover it with soil and branches to disguise it. The older sister Eden believes that her younger brother Hyunho suffers from EMF sensitivity. However, Hyunho himself believes otherwise: that his condition has nothing to do with it. Hyunho misses the city life. Hyunho decides to go off course and goes down to the city, to a highway service station. He experiences an excruciating headache and faints. Eden carries Hyunho back to the forest, sets up a tent in a safe place, lies his younger brother down, then sneaks into a nearby village to steal medicine from a pharmacy. On her way back to the woods, Eden is confronted by tall standing, never-ending, peculiar looking lights.
