When Night Meets Day

S9, E21: In the Emmy Award-winning series' landmark 200th episode, an innovative dual storytelling device contrasts Pratt's night shift with Carter's day shift. On the night scheduled to be his last in the emergency room, Pratt treats a woman whose unborn child was brutally cut out of her, prompting a search for the baby. He also takes care of a burned firefighter and victims from a mass cult poisoning related to the day's unnerving solar eclipse. Pratt relays the patients to Carter, whose frustration grows as he treats two of the cult members, a wounded gang member, a dying Buddhist nun and a heart attack victim. Meanwhile, Romano experiences what it's like to be a patient when he undergoes surgery.
