Dr. Cal  Lightman, Chef der Lightman Group, ist ein menschlicher Lgendetektor. Genauer als jedes Gert wei er, wann der Mensch ihm gegenber lgt. Er glaubt es nicht nur, nein, er wei es genau. Jede klenste Bewegung, ein Rmpfen der Nase, ein Schlucken zum falschen Zeitpunkt, das Heben der Augenbrauen - alles sind fr ihn Hinweise. Seine Talente und die seiner Mitarbeiter werden von den den verschiedensten Behrden/Personen angefordert. In der Pilotepisode soll er zum Beispiel einschtzen, ob ein 16 jhriger Schler seine Lehrerin ermordet hat oder ein Mitglied des Congresses eine Beziehung zu einem Callgirl unterhlt.
