Carol (Julianna Margulies) comforts a security guard (Michael Rapaport) as he lies dying from severe chemical burns. The other staffers tend to a young man (Keith Bogart) who fell 75 feet into the Chicago river. Also part of the ER caseload is an elderly couple who may or may not have AIDs, and a heroin-addicted infant named Josh McLean. And elsewhere, Benton (Eriq La Salle) is none too happy that Carla (Lisa Nicole Carson) has invited her boyfriend to Reese's baptism. ~ Hal Erickson, Rovi
