This 200th episode of ER (actually the 201st in the syndicated package) occurs during a solar eclipse, with the action alternating between the day and night shifts at County General. Holding down the day shift is a bone-weary Carter (Noah Wyle), who must contend with the victims of a cult mass suicide, among many other trying cases. And during the night shift, Pratt (Mekhi Phifer), ostensibly making his final round as a resident, is "redeemed" as he treats a woman whose unborn child was viciously cut from her womb. In other developments, Corday (Alex Kingston) tries to ease the mind of Romano (Paul McCrane) as he prepares to have his injured hand and forearm amputated; and the ER receives an urgent phone call from Kovac (Goran Visnjic) in Africa. ~ Hal Erickson, Rovi
