Watch the Good Nurse on Netflix

An infamous caregiver is implicated in the deaths of hundreds of hospital patients.

Amy Loughren (Chastain) is a nurse at an average New Jersey hospital, trying to balance being a single mother with her high-stress job.

Amy, a compassionate nurse and single mother struggling with a life-threatening heart condition, is stretched to her physical and emotional limits by the hard and demanding night shifts at the ICU.

But help arrives when Charlie, a thoughtful and empathetic fellow nurse, starts at her unit.

While sharing long nights at the hospital, the two develop a strong and devoted friendship, and for the first time in years, Amy truly has faith in her and her young daughters’ future.

But after a series of mysterious patient deaths sets off an investigation that points to Charlie as the prime suspect, Amy is forced to risk her life and the safety of her children to uncover the truth.

This gets even harder when she’s diagnosed with a cardiac condition that could kill her if she doesn’t get a heart transplant in time.

She keeps the diagnosis from her bosses, staying on at work because she hasn’t been there long enough to get the health insurance needed to deal with it.

The heart issue adds a ticking time bomb aspect to The Good Nurse in that if the tension of what’s about to happen causes too high a heart rate in Amy, she could die.

Charles Cullen (Redmayne), a new nurse befriends Amy and offers to help her with her patients, and even with taking care of her children.

At first, Charles seems like a lifesaver, a colleague who knows Amy’s secret, and wants to be there to help.

Amy has no idea that the hospital, led by an icy Kim Dickens as its callous representative, has alerted the 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 was clearly double dosed, and the hospital really only let the cops know so they could be prepared for any legal liability.

And then another one of Amy’s patients dies.

A young mother who’s survived an accident also dies unexpectedly—as do many more patients who were seemingly on the road to recovery.

The investigating officers, played by Noah Emmerich and Nnamdi Asomugha, start digging a little deeper and find a disturbing work history for Mr. Cullen involving nine other hospitals, all of which he left with rumors swirling.

Neither patient is based directly on any of Cullen’s known victims
