Angels of Mercy ER charge nurse Nora Halloran has been living with a painful secret for two long years. But when a coworker is brutally assaulted and killed, she knows she can no longer remain silent.
Determined to unmask the murderer, Nora teams up with her friends— Lydia, an ER attending doctor with a secret of her own; Gina, the once-cocky resident struggling to strike a balance between her family and her job; and Amanda, a med student caught between her career and her conscience.
As the victim count grows, Nora must face her deepest fears and reveal all her secrets to save the man she loves and stop a monster.
