Having endured four consecutive night shifts, Greene (Anthony Edwards) reluctantly tackles night number five with only a skeleton crew -- and an inordinately large influx of patients. Among those passing through the doors of the crowded ER are an abusive husband whose wife has retaliated in a violent fashion, a lap dancer, a teenager who has swallowed antifreeze, and a young girl who was injured in a car accident that Greene had witnessed while grabbing a sandwich at a nearby restaurant. At the end of it all, Carter (Noah Wyle) can only express admiration for Greene's handling of a near-impossible job -- not to mention a last-minute innovation in patient care. ~ Hal Erickson, Rovi
