A dramatic series about a former police officer who is a "human lie detector," that is, an expert in reading facial and body language that gives away deception. He partners with a female clinical psychologist and opens up an agency that offers private investigation and crime solving.
Tim Roth stars as Dr. Cal Lightman, the world's leading deception expert who studies facial expressions and involuntary body language to discover not only if someone is lying, but why. Based on the real-life scientific discoveries of Dr. Paul Ekman, the series follows Lightman and his team of deception experts as they assist law enforcement and government agencies to expose the truth behind the lies.
