When you scratch your chin, wring your hands, wrinkle your nose, or swallow too much, Dr. Cal Lightman knows you're lying. He doesn't just think so, he knows so, because he's taken his exceptional skills of observation to become the foremost deception expert in the country. Being a human lie detector, Cal can uncover the deepest secrets and crack the hardest cases.
Any watchers? I think its cool because it's loosely based on a real guy and in the episodes they often cite real life examples (pictures of a well known people exhibiting facial expressions that indicate lying).
