Lewis (Sherry Stringfield) feels she is under attack from all sides when Kayson (Sam Anderson) draws up charges against her vis-à-vis the Vennerbeck death, and ER chief Morganstern (William H. Macy) reprimands her for her lack of self-confidence. Elsewhere, Greene (Anthony Edwards) tends to a human "mule" who has secreted a half-kilo of cocaine in his stomach. Benton (Eriq La Salle) conducts a desperate search for his missing mother. And Carter (Noah Wyle) offers to help fellow med student Deb (Ming-Na) as she deals with an emotionally disturbed patient. ~ Hal Erickson, Rovi
