Horror. Suspense. Thriller. Young Adult Fiction. At the movie theater where Jo works, the last show has ended. But the nightmare is just beginning. Tonight, Riverview Theaters is closing forever, the last remaining business in a defunct shopping mall. The moviegoers have left, and Jo and her six coworkers have the final shift, a shift that quickly takes a dark turn. First a stranger arrives with a chilling accusation. Then the power goes out and their manager disappears, along with the keys to the lobby doors and the theater safe, where the crew's phones are locked each shift. Their tension turns to terror when Jo discovers the dead body of one of her co-workers. Now their only chance to escape the murderer in their midst is through the dark, shuttered mall. With its boarded-up exits and disabled fire alarms, the complex is filled with hiding places for both pursuer and pursued. In order to survive this night, Jo and her friends must trust one another, navigate the sprawling ruins of the mall, and outwit a killer before he kills again.
