Halloween at Chastain proves to be just as spooky as ever when Conrad is tasked with diagnosing a young woman admitted to the hospital with extreme night terrors. Meanwhile, Devon faces his first Halloween in the ER, Nic panics over her decision to bring her newly sober sister to Mina's epic annual Halloween party and Bell finds an interesting way to make use of his new assistant.
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.
