Math Professor Sophie Knowles is looking forward to some time off for the summer, but things do not go as planned. The graduates are complaining about the mayor who gave the commencement address, one student is upset about her grade and vents on social media, and just when she is about to escape all of the drama to take a stroll with her helicopter pilot boyfriend, they're interrupted by the mayor himself as he falls into the campus fountain with a knife in his back. Sophie dives into all the scandal and corruption that seems to connect to the mayor and finds his killer.
