It's a December blizzard, and the day starts out quiet. Hathaway announces her engagement with Tag. Suddenly, County General goes into crisis mode when a 32-car pileup on an expressway inundates them with patients. Among the patients are a young male that Benton knows that lost his leg, a patient of Ross' that dies suddenly while waiting for treatment, and a man who is snowed in at home and calls Greene when his wife refuses to go to the hospital to have her baby. Lewis tries to save a man that suddenly develops an aneurysm, and the patient is saved by the most unlikely person.
