When a nasty flu season turns out to be masking a terribly infectious disease, Chastain must race to quarantine and diagnose infected patients. Mina finds herself testing Quovadis medical devices in an effort to defend Dr. Austin, who, feeling responsible for the death of a patient, is serving penance by staying away from the OR. Conrad is prepared to take the next step with Nic, but finds that she may not be as ready.
Conrad Hawkins is one of Chastain Park Memorial Hospital's best doctors. Charming and arrogant, Conrad likes to take an unconventional approach whenever possible and believes it's his personal duty to shatter the romantic illusions of the first-year residents. Dr. Devon Pravesh is an innocent idealist who leans on his finely tuned moral compass, but with Conrad's help, he begins to realize that the practice of medicine is a business, like any other, with less-than-angelic patients and fallible doctors. Lives may be saved or lost, but expectations will always be shattered.
