When Lupo and Bernard come upon the burning body of Cesar Ramirez (Noel Rodriguez), a sixteen-year-old charter school student from a bad neighborhood, they begin to question his young mentee Moses (Aaron Shaw), who was the last person to see him alive. After evidence leads the detectives to a shocking cell phone video of the crime being committed, they soon realize that the four people in the video may be in cahoots with an unexpected ally. The investigation leads the detectives to the high school principal, Martha Woodside (Debra Winger), who has all of the right answers. With a shady educator, tampered alibis and jealous schoolboys all coming into play, the detectives discover that their case may be more than elementary, and until new evidence comes to light, there is no one that ADAs Cutter and Rubirosa can put on trial.
