Entering its intriguing second season, LIE TO ME continues with new cases, new lies and life-changing situations for The Lightman Group as they encounter new cases, including a woman with multiple-personality disorder (Erika Christensen, Traffic) whose lies as one personality may be true for another personality. Additionally, Lightman will work to solve a homicide while held at gunpoint during a hostage situation. He will also struggle with his rival, who stirs up trouble and creates tension among Lightmans employees. These cases require the team to look further and search deeper, not only to determine who is lying but why. In their personal lives, after Fosters marriage collapses, she explores the possibilities of life as a single woman, while Lightman tries to come to terms with his own mysterious past.
