Colvin College is still reeling from the fire that destroyed the administration building last semester, and put a student, Margot Miller, in a coma, when Professor Moynihan announces he will be offering his famous "History of Lying" seminar to a select number of students. Cat Carlson is thrilled to be accepted into the course: Moynihan is a celebrity on campus and is releasing his very own lie-detecting technology, CUFF, later in the year. But the class—"The Liars' Club"— discovers Professor Moynihan has his own agenda.
