They're young, smart, mostly beautiful graduate students naive enough to believe they can make a difference. Little did they know the most important lesson they'd learn is how to stay alive. The first day of class for Ian Joyce and Sarah Gold starts like any other, until a fellow student, Jake Havens, pulls a wrinkled envelope from his jacket. Inside is a blood-stained scrap of shirt from a boy murdered 14 years ago and an anonymous note taking credit for the killing. The only problem is the man convicted of the murder is already dead. Suddenly, the class has a new assignment: find the real killer.
