Amy Loughren (Chastain) is a nurse at an average New Jersey hospital, trying to balance being a single mom with her high-stress job. It becomes even more difficult when she is diagnosed with a heart condition that could kill her if she does not receive a heart transplant in time. She hides the diagnosis from her bosses, staying at work because she hasn’t been around long enough to get the health insurance needed to deal with it. The heart problem adds a ticking time bomb aspect to “The Good Nurse” in that if the strain of what’s about to happen causes Amy to get her heart rate too high, she could die.
She thinks the opposite will happen when she meets kind Charles Cullen (Redmayne), a new nurse who befriends Amy and offers to help her with her patients, and even take care of her children. children. At first, Charles seems like a lifeline, a co-worker who knows Amy’s secret and wants to be there to help her. Amy has no idea that the hospital, run by a frosty Kim Dickens as a callous representative, has alerted local authorities to a concerning situation involving the inexplicable death of one of Amy’s patients. With little warning, a woman coded and an abnormal amount of insulin was found in her system. She clearly received a double dose, and the hospital is only really letting the cops know so they can be prepared for any legal liability. Investigators, played by Noah Emmerich and Nnamdi Asomugha, begin to dig a little deeper and find a disturbing work history for Mr. Cullen involving nine other hospitals, all of which he left with rumors swirling. And then another of Amy’s patients dies.
Would Charles Cullen, who is confirmed to have killed at least 29 people, but it is suspected there could be hundreds, would he ever have been caught if not for the courage of someone within the system ? The truth is, the lawsuit-terrifying ops that hired and fired Cullen didn’t come close to fulfilling their moral duties, pushing a serial killer toward his next victim. And as long as that kind of corporate ethics principle was in place, Cullen could have continued. Lindholm was clearly drawn to the heroic arc of this true story, the one person who broke the pattern by helping the authorities, even though it was so risky to do so.
