Have you ever seen a movie titled "Lie to Me" ? If so, you must be familiar with the name of 'Dr. Cal Lightman' mustn't you ?
He knows when a person do lie just by looked their face, how's the story ?
Here, I give the synopsis :)

In Lie to Me, Tim Roth plays Dr. Cal Lightman, a scientist specializing in decoding facial expressions and body language.
He's bursting with fun facts, asserting that there are, on average,
"three lies per 10 minutes of conversation." Like Monk and Psych and The Mentalist, Lie offers us an eccentric who's brought in by law enforcement to solve crimes. He's got a British accent, so we know he's intelligent and a bit dotty.
And he's got an attractive female associate (The Practice's Kelli Williams) who's also full of fun facts: "In a fake smile, there's no eye-wrinkling."

Naturally, Dr. Lightman encounters skeptics who call him a "carnival act", just as naturally, he proves them wrong.
Lie to Me is derivative yet well crafted, predictable yet ever-so-slightly novel (all those new fun facts!), so it's no wonder that Fox thinks it's got itself a potential hit worthy of post–American Idol time-period status.
