The film begins with a premise rooted in economic vulnerability: four strangers volunteer for a "paid research study" for quick cash. This setup mirrors real-world social psychology experiments, such as the Milgram or Stanford Prison experiments, where authority figures manipulate subjects under the guise of science. In The Killing Room , this "choice" is a facade; the participants are immediately stripped of their agency when a sudden act of violence—the execution of one subject—transforms a survey into a lethal game of survival. 2.
