It's Saturday morning at Ashton High School, and the SAT exams have just begun. As the students settle in to their seats, cracking open their exam booklets, everyone is startled by a loud crash and the wail of a car alarm. Rushing to the window, they are shocked to find the body of beloved English teacher Beth Landow strewn across the hood of a car parked at the base of a clock tower. It appears to be a suicide. But school principal Arlene Cassidy isn't so sure. That's why she calls on the services of detective Adrian Monk to investigate. Andrew McCarthy guest stars.
