Jessica returns to her college town when a sorority sister calls to tell her that one of their much-loved professors, Leon Walker, has been arrested for the murder of a student. Walker has confessed to the killing and her old classmate - and now District Attorney Paul Robbins - feels he has no choice but to proceed. Jessica soon realizes that Walker's story just doesn't add up and that he is obviously protecting someone. When someone else confesses to the crime, Jessica realizes why Walker was prepared to take the blame but even that doesn't quite provide the solution to the crime.
