Loosely inspired by the career of psychologist Paul Ekman, this engaging crime drama focuses on the work of Dr. Cal Lightman (Tim Roth), whose knowledge of human facial and behavorial cues lets him determine whether a person is telling the truth. Along with colleague Dr. Gillian Foster (Kelli Williams), Lightman specializes in assisting police agencies with cases where detecting duplicity can be the critical factor in solving crimes.
