The story

What Is The Lie Detector About?

The premise of The Lie Detector without spoilers.

In the early 20th‑century rush of scientific breakthroughs, researchers announced a machine that could detect lies – the polygraph. Celebrated as a crime‑fighting marvel, it entered police work, media, and even marital tests, while corporations and governments used it to gauge honesty and loyalty. The film follows how this well‑intended technology morphed into a tool of fear, intimidation and moral ambiguity. Written and directed by Rob Rapley, with executive producer Cameo George, it explores the unintended consequences of the lie detector’s promise.
