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.
Bell grows frustrated when Marshall Winthrop, Conrad’s dad and new chairman of the board, requests Conrad’s input in his discussions about the hospital’s expenses. As Conrad and Nic work to cut costs for their patients in need, Julian Lynn, a sharp and sophisticated medical device rep, meets the staff at Chastain and inserts herself into the ongoing work of the doctors to promote her costly products.
Nic and Conrad contemplate their past when they team up to diagnose a happy husband and wife who are both admitted to the hospital with mysterious symptoms. Bell and Marshall butt heads on a work trip when their cut-throat business tactics don’t align.
Chastain is flooded with concert goers when a stampede at a music festival grounds leaves many in need of doctors. As Conrad and Nic race to help Josh Robinson, a professional adventure guide with a long list of prior injuries, Devon works with a musician who swears he is sober, even though his toxicology report suggests otherwise. Meanwhile, Bell stirs the pot when the hospital’s revered orthopedic surgeon, Dr. Kit Voss, demands a better resident, Julian works to get her boss on Bell’s good side and Winthrop continues to push Conrad to believe he’s a changed man.
When Bell makes the executive call to utilize Julian Booth's medical devices, rather than the hospital's usual products, Kit and AJ must stop their momentary feuding in order to team up against him. Elsewhere in the hospital, Conrad and Nic work to make a child's dreams come true after finding out his cancer has returned and the rest of the staff takes notice of Julian and Devon's new friendship.
