Eight weeks after attempting suicide, head nurse Carol (Julianna Margulies) returns to work at the ER. Meanwhile, Greene (Anthony Edwards) forces a family to come to grips with a domestic abuser in their midst. And Carter (Noah Wyle) learns a lesson in compassion from a mysterious female patient (played by Rosemary Clooney, the aunt of series regular George Clooney), who bursts into song at the slightest provocation. ~ Hal Erickson, Rovi
