Mara Bennett, the new ER resident everyone calls a lazy nepotism hire, gets an ultimatum from her chief: one more mistake and she's fired. But the """"slacker"""" is a hidden genius—she catches a liver laceration and a vascular anomaly no one else saw, reads a concealed third-degree heart block in a flatline and brings back a patient her chief had already given up on, and matches the diagnosis of a 30-year teaching-hospital veteran. After reviewing every case she's handled with zero errors, the chief withdraws the firing threat: the ER can't afford to lose her. And the director's cryptic warning hints at a secret far bigger than anyone knows.
