[1][2] In 1940s Thailand, a krasue lives a normal life as a woman by day, but at night her head detaches from her body and seeks out for flesh and blood.

Noi and Sai decide to hide inside the house that supposedly contains the spirit of a Krasue that protects the forest.

When Sai visits Jerd he begs her not to leave him as she had planned to run away with Noi to Bangkok that evening.

Sai's father takes her to a mass movie theater in the village borders to show everyone that the rumors about her turning into a krasue at night are false.

The monk whose guidance Noi has been following all this while reveals that in the ancient time a krasue, wife of a krahang fell in love with a human who made her pregnant.

He had helped Noi because he was guilty of locking his wife in a box in the forest to prevent her death and didn't want the same thing to happen to Sai.

Meagan Navarro of Bloody Disgusting recommended the film, writing: "Inhuman Kiss does run a bit overlong and has a measured pace, but it builds into an insane climax.

"[4] A sequel entitled Inhuman Kiss: The Last Breath (Thai: แสงกระสือ 2) was completed in 2022 and released in Thailand on 30 March 2023.
