Lie to Me (stylized as Lie to me*) is an American crime drama television series. It originally ran on the Fox network from January 21, 2009 to January 31, 2011. In the show, Dr. Cal Lightman (Tim Roth) and his colleagues in The Lightman Group accept assignments from third parties (commonly local and federal law enforcement), and assist in investigations, reaching the truth through applied psychology: interpreting microexpressions, through the Facial Action Coding System, and body language.
