Art of the Devil 2 also known as Long Khong (Thai: ลองของ) is a 2005 Thai supernatural horror film directed by Kongkiat Khomsiri, Art Thamthrakul, Yosapong Polsap, Putipong Saisikaew, Isara Nadee, Pasith Buranajan and Seree Pongniti (known collectively as the "Ronin Team").
Two years ago, six school friends – Ta, Kim, Por, Tair, Noot, and Ko – were faced with a grudge.
The tomboyish Tair and stylish singer Noot might be lovers (though this is never made clear), and Ko is their fun-loving friend.
Miss Panor, who is embarrassed at her sexual exploits being revealed, is found stabbing herself repeatedly in the legs.
Upon arrival at Panor's cottage on the river, Noot's cell phone rings; her uncle wants her to return because her father is in the hospital, so she makes her goodbyes and heads back to the city.
Miss Panor is a polite hostess (if a little distant), and Ta's great-grandmother seems harmless enough, though he warns everyone that she is a bit senile.
As the group stays at the cottage, Kim experiences some strange occurrences around it such as, the door moving on its own, a white figure appearing underwater, and witnessing Ta's great-grandmother devouring a cat.
Miss Panor retires to a secret hut in the jungle, where she has several corpses gathered round, all of them sitting at desks, like students.
The group realizes that the meat, which is actually dismembered body parts added in the soup, is in fact, Noot.
It is implied that after Noot left the cottage, she was captured, tortured, killed, and dismembered by Miss Panor.
The driver takes a fatal fall from the boat after seeing Miss Panor coming towards him from the other side, which sinks.
In the vision, Panor is shown torturing Ta's father by ripping off his toenails, on the premise that if she hobbles him, he can't leave her.
Ko threatens Tair with the gun, but suddenly starts to writhe and flail as dozens of geckos claw their way out of his body, killing him.
After seeing Kim as a walking corpse and in hysterics, Tair gouges and rips out her own eyes, ultimately killing herself.
She stabs him in the neck with a syringe full of a paralytic agent, then pours boiling water down his throat and slowly burns every inch of his skin with a blowtorch.
In the secret jungle hut, Miss Panor is performing CPR on fatally burned Por in order to inflict more torture on him.
As they chat, the TV in Kim's room broadcasts a news show, which reports that the five students who visited Miss Panor are dead.
It was Ta's great-grandmother who had told Panor that in order to break the spells placed on her she had to kill the shaman that was paid to perform them and eat his flesh.
The film ends with Kim jumps out of the hospital window to her death, holding the clay doll the shaman gave her.
