When law professor Natalie Greco agrees to teach a class at a local prison, her world gets turned upside down. A violent riot breaks out during her class. When Nat rushes to help a grievously injured prison guard, he asks her to deliver a cryptic message with his last words: "Tell my wife it's under the floor." This dying declaration plunges Nat into a nightmare where she finds herself a suspect in a murder and encounters threats to her life.
