Prangthong Changdham

A group of friends from Bangkok decide to visit an abandoned house inhabited by a spirit who has the power to grant wishes, if promised the appropriate offering. With their graduation getting closer and closer, most of them pray for decent grades, but one of them, a skeptical girl called Moss, makes a mocking pledge that she will do anything in return for the satisfaction of her friend's desires. while their friends are careful to make sure they provide the promised offerings as their wishes are fulfilled, Muay, Pin, and Moss are not so diligent. Before long all three are subjected to a series of bloody manifestations, courtesy of an angry and vengeful spirit determined to collect what is owed.

Set in early King Rama V era, former British soldier Peter Bain is busted for trying to sell defective firearms to influential Chinese merchant Yang. Forced to hunt wild game with these firearms along with Yang's men, Bain links up with ex-monk Wan and Karen-American hunter Julia, who he meets on the way to the jungle. The group sets off to hunt an elephant, said to be protected by a ghostly tigress that can transform itself into a woman. The tigress is supposedly possessed by the revengeful spirit of Nian, a woman who was tortured and killed in the King River Battle almost a century earlier. As Wan learns more about the tigress myth, he tries to release Nian's spirit, but Yang's men want to destroy Nian and get the elephant. With greed, resentment, and karma from past lives encircling the group, violence is surely around the corner.
