Natalie Greco loves being a law professor, even though she secretly feels like Faculty Comic Relief. She loves her family, too, but as a bookworm, doesn't quite fit into the cult of Greco football, headed by her father, the team captain. The one person whom she feels most connected to is her colleague Angus Holt, a guy with a brilliant mind, gorgeous façade, and a penchant for helping those less fortunate. When he talks Nat into teaching a class at a local prison, her world turns upside down. A violent prison riot breaks out during the class, and in the chaos, Nat rushes to help a grievously injured guard. Before he dies, he asks her to deliver a cryptic message: "Tell my wife it's under the floor."Plunged into a nightmare, Nat suddenly finds herself suspected of a brutal murder and encounters threats to her life.
