Art of the Devil ( or Khon len khong) is a 2004 Thai horror film directed by Tanit Jitnukul. It has two titular sequels, Art of the Devil 2 (2005) and Art of the Devil 3 (2008), but these films feature a different story with new characters.

Plot

Art of the Devil tells the story of Boom (Supaksorn Chaimongkol), a young Thai girl who meets a married man named Prathan (Tin Settachoke) and his male friends at a country club where she works. The two soon begin an affair, and Boom finds herself pregnant afterwards. When she breaks the news to Prathan, he was initially not elated about the pregnancy, and questions Boom if he is the real father of her baby. Then Prathan inquires Boom how much money she needs in exchange for her silence, to which Boom disappointedly requests for a large sum. After giving her the required sum, Prathan appears to have a change of heart, reassuring Boom that he will not leave her.
