The math is horrifying.
Armed with video cameras, three friends venture into a dark forest in an attempt to capture paranormal activity.
The leader of the gang suggests performing a ritual to summon a pontianak, a vampiric female ghost found in Malay and Indonesian mythology.
One of them is reluctant but they perform it anyway. Nothing happens. Then suddenly one of them goes missing. After a futile search, the other two return home, and a prank is uncovered.
But then something horrifying happens.
