Art of the Devil 2

During their final high school year, Ta, Kim, Por, Tair, Noot, and Ko become entangled in Ta's family's secrets. Panor, Ta's father's wife and their former teacher, seduces Por; the group learns Panor is also married to Ta's father and having an affair with the sports coach. They hatch a plan to film the infidelity and broadcast the clip to the entire school.

During the confrontation, the coach uncovers the group's plot and holds them at gunpoint. He sexually abuses them, with Noot the most frequent target. The assault marks a turning point that drags the friends into a cycle of fear and retaliation.

The students seek revenge and visit a Shaman who agrees to curse the coach. The Shaman warns that black magic, once unleashed, will haunt them forever: 'Once you start, it will follow you till you die'. The warning lingers as events unfold.

The curse extends to Panor; the coach dies in a gruesome display as fish hooks emerge from his body, while a healer tries to mend him. Panor retreats to a riverside cottage, tormented by the consequences of the curse.

In the present, the six friends reunite to visit Ta's father's ashes mausoleum and to pay respects to Panor. They also visit Panor's cottage, where unsettling rumors begin to surface.

Noot experiences doors moving on their own, a white figure underwater, and Ta's great-grandmother appears harmless but is secretly senile. The eerie events hint at Panor's lingering influence in the house.

Panor retreats to a hidden jungle hut where she keeps several corpses seated at desks with photos identifying the former students. The scene hints at her control over the fates of the group.

At dinner, Panor's soup contains dismembered body parts. Each student recognizes a remnant from their past, revealing that the meat is Noot, who was captured, tortured, and cannibalized by Panor.

The group uncovers a video camera recording Panor killing and cannibalizing the Shaman, then advancing on the person holding the camera with a tree branch. The footage confirms Panor's monstrous acts and the danger surrounding them.

Tair begins to hallucinate rotting corpses while Ko is killed when dozens of geckos burst from his body. The youths seek refuge at the dusty shrine to hide from Panor.

The group splits up; Por and Ta go after Panor while Kim and Tair stay outside the shrine. Kim follows into the jungle, and Ta and Por experience visions of Panor.

Por locates Panor in her hut and is tormented with visions that hamstring him and rip out his teeth. He admits that a love spell he cast lured Panor into infidelity and filming, and that he then punished her with a painful curse.

Miss Panor arrives, binds Por, and drags him to her secret hut. She stabs him with a paralytic syringe, then pours boiling water and scorches his skin with a blowtorch as police close in outside. A raid erupts and Panor is fatally shot.

Kim encounters Ta's burned spirit; he explains that the video of Panor devouring the Shaman was shot by Ta's father, who threatened divorce after seeing the tape. Panor tortured him before he killed himself, and the chain of spells links back to the group. Ta's vengeful spirit lured the friends into reliving his pain and sacrificed himself to save Kim.

A school flashback reveals Kim and another classmate once fancied Ta; Kim visits the Shaman again and receives a clay doll. In the closing scene, Kim leaps from the hospital window clutching the clay doll, while Ta's burned figure lies beside her, confessing his unwavering love.
