When Liza turns to an old classmate to find out who is behind these political shenanigans, Liza discovers that he's been murdered and that his terrifying problems have now become hers. Still, he's left his share of clues behind. Liza needs to unravel them fast, before someone uses her run for mayor to run her into the ground.
