DR. CORDAY MAKES EMOTIONAL RETURN AND DR. PRATT CAUSES MORE PAIN WITH RESUSCITATION

Chaos reigns as the ER is overloaded with patients after another hospital is shut down just as Dr. Corday (Alex Kingston) makes an emotional return -- and the aggressive Dr. Pratt (Mekhi Phifer) enrages his counterparts when he resuscitates a heart attack victim who had been pronounced dead. As the tight-lipped Corday sees the ER for the first time since Dr. Greene's death, she clashes with the tightly wound Dr. Weaver (Laura Innes). Meanwhile, Dr. Carter (Noah Wyle) and a frisky Abby (Maura Tierney) hardly care to conceal their growing romantic attraction to each other; Dr. Gallant (Sharif Atkins) gets an eye-opening education when he pulls a shift in the psychiatric unit; Dr. Romano (Paul McCrane) faces a daunting new challenge. Goran Visnjic, Ming-Na and Sherry Stringfield also star.
