The movie is set in 1972[3] in a remote farming village in Thailand's Kanchanaburi province, centering on a family of eight — the parents, their three sons Yak, Yos, and Yod, and their three daughters Yad, Yam, and Yee.

Yak puts his hand on a flame and Yad bites herself to force themselves to remain conscious while they wake the others and manage to bring Yam back.

Left with no choice, the family calls a priest, Mr Puth, for help, and he instructs them to cut down a bamboo tree near their house.

Yak, Yod, Yad, and their mother bring Yam to the nearest hospital in their truck, with Sarge and Mr Puth accompanying them; their father, Yos, and Yee remain at home.

After Yak regains consciousness, he confronts his possessed sister, who uses his handgun to shoot Sarge and threatens to kill their other unconscious family members.

Yad awakes and stabs Yam in the arm with a knife, causing the evil spirit to temporarily leave her body.

Jampa Saenprom, who portrayed the crazy old woman Chuay in the movie, had previously appeared in many other films, but she felt that audiences remember her more for her role in Death Whisperer.

She said the most difficult scene was the one where she performed a black magic ritual and had to urinate in a baat (monk's alms bowl), which Thai people consider sacred.
