As Conrad battles a group of overly aggressive attending physicians on behalf of a patient with a mysterious chronic ailment, he also must face off against his father who has shown up at the hospital unannounced. When Mina goes out of her way to help a young man from her neighborhood who almost mugged her, Nic offers her assistance and discovers a secret that Mina has been keeping behind closed doors. While away from the hospital, Nic enlists the help of Devon to keep an eye on Lily, which leads him to an incredible find that has him questioning Dr. Lane's motives. Also, Renata's plans to poach a renowned surgeon from another hospital hit a standstill when Bell decides he doesn't agree with him.

A blackout at Chastain Memorial Hospital requires the staff to treat their patients without the help of any technology. Bell orders the staff to stop accepting new patients and transfer those on life support, but when a child in need is rushed to the ER, Conrad and Devon go against the mandate. Meanwhile, Mina and Austin are tasked with performing heart surgery on a premature baby, despite the lack of power, and Nic works tirelessly to organize the staff and patients who stay during the blackout.
