HALLOWEEN TURNS DANGEROUS IN E.R. WHILE DOCS RUSH TO STOP FLESH-EATING DISEASE

A suspicious fire on Halloween floods the E.R. with many bizarrely costumed victims -- some of whom offend Dr. Pratt (Mekhi Phifer) -- while a frustrated Dr. Romano (Paul McCrane) lets his recent traumatic injury interfere with good judgment when he directs Dr. Corday (Alex Kingston) during surgery on a man with a flesh-eating infection. Elsewhere, Nurse Marquez (Laura Ceron) threatens to file a grievance against Dr. Kovac (Goran Visnjic), who must also treat an older mother (guest star Ashley Gardner) who won't accept that her newborn baby cannot survive while Abby (Maura Tierney) and Dr. Carter (Noah Wyle) playfully dress up in suggestive seasonal costumes. In addition, the staff greets an older but wiser surgical intern (guest star Don Cheadle) who tries to overcome a daunting physical handicap. Laura Innes, Ming-Na and Sharif Atkins also star.
