Lie to Me (2009)

Dr. Cal Lightman can detect the truth by analyzing a person's face, body, voice and speech. When someone shrugs one shoulder, rotates their hand or raises their lower lip, Lightman knows they're lying. By analyzing facial expressions, he can read feelings – from hidden resentment to sexual attraction to jealousy. But as Lightman well knows, his scientific ability is both a blessing and a curse in his personal life, where family and friends deceive each other as readily as criminals and strangers do. Lightman is the world's leading deception expert, a scientist who studies facial expressions and involuntary body language to discover not only if you are lying but why.
