A newly engaged couple, Stella and her fiancée Rimson, disappears on a trekking trip in a virgin forest.

They finally reach the forest's entrance, only to find the passage blocked, inducing them to continue their journey by climbing the hilly road into the deep woods.

In the climax, they manage to exit the cave with a warning: Samantha must go to the house of Mbah Putri, the origin of the Kuntilanak's wangsit in the Mangkoedjiwo family.

As they set up to camp at the clearing, Samantha explains her reason for coming here and ominously proclaims they have arrived at "Ujung Sedo".

Samantha comes across Yenny, follows her to a field with fallen leaves, and sees a group of blind children running after a white horse.

Chasing after them, Samantha manages to find Yenny and, while hiding, witnesses the Kuntilanak's deed of collecting children to suck off their souls as sustenance.

The Kuntilanak was the vengeful spirit of a mother killed after giving birth to the devil's child, whose fate was similar to the former.

The Kuntilanak replenished the strength of the devil's spawn, using murdered victims' souls to enable it to stay alive in Mbah Putri's womb.

Sam's encounter with Mega was an illusion created by Mbah Putri to lure Samantha to Ujung Sedo and become the replacement host.
