The haunted become the hunted. In this horror film set in Malaysia, a Japanese-American woman's recurring nightmare drives her to Pontianak on the island of Borneo where she thinks her dead birth mother is calling to her. Charity and three friends, plus a local guide, head for the jungle river but their all-terrain vehicle breaks down on the way and they are forced to trek through the jungle to find the river. Eye, the local guide, fully aware there are ghosts in the jungle, proceeds cautiously, but Charity and her friends have yet to be convinced these things really exist. When a woman mysteriously appears near an abandoned hut, an old man appears as well, and the trekkers helplessly watch as he beats her inside the hut. It is after this that the horror turns on Charity and her party, and the killings begin. The link between Charity's nightmares that sent her to Borneo and the horrors that visit the group is an unsolved mystery but hinted at as part redemption and part revenge.
