Dr. Lightman believes that everyone lies. And to prove it, he only needs a couple of minutes to talk with someone. Any movement, gesture, or careless word can reveal you to be a liar. You just need to know how to see it. The average person lies three times in ten minutes of conversation. The task of Dr. Lightman and his colleagues is to detect this lie, and, using their talents, they save the innocent from prison and put criminals behind bars. The Lightman Agency is sought for help by federal authorities, the government, Congress, and even the Prime Minister of Uzbekistan. But can a person be happy if they see that everyone around them is constantly lying?
