In Bangkok, five former high school friends are informed that the father of their friend Ta committed suicide. Ta is the son of Prowaet, who got married with their English teacher Panor and together they had a son, Nong. The student of medicine Kim and her boyfriend Por that studies in law school, the student of engineering Ko and Noot that is studying English to move to Australia with her gay friend Tair decide to reunite and travel to the country for the ceremony of cremation. While traveling by train, Kim recalls an incident two years ago in their last year in school, when they had been abused by their couch and lover of Panor when they found their affair. The students, seeking revenge, asked the Cambodian voodooist Pawn to cast a black magic against the couch, who mysteriously died after fishing. Once in the village, they spend the night with Ta and his stepmother Panor in their isolated house in the jungle nearby a river, when creepy things happen and their horror begin.<br /><br />"Long Khong" is a creepy, gruesome and gore tale of witchcraft and insanity. The story is really scary, and has some nasty and cruel scenes: the worst is the sequence when the teenager is tortured with hot water and burned by a torch. The story follows the pattern of the good Asian horror movies, with secrets and revelations being disclosed in the last moments, like the last parts of a puzzle. This macabre type of voodoo with corpses is unusual in Western movies. The screenplay is very well tight, with great lines, and I liked the wise thought of Kim: "The future is what we want to be; the past defines us". The direction is very precise, the special effects are impressive and the cast has great performances. The lead actress is extremely gorgeous, and unfortunately I do not know her name. My vote is seven.<br /><br />Title (Brazil): "A Arte do Demônio" ("The Art of the Devil")
