Alan Young guest stars as Archie Mellonston, a nursing-home patient who raises a ruckus in the ER when he flashes back to a traumatic incident during the Korean War. Other developments: blacklisted throughout Chicago by the vengeful Romano (Paul McCrane), the unemployed Benton (Eriq La Salle) is saddled with additional problems courtesy of his pugnacious nephew Jesse (Andrew McFarlane); Greene (Anthony Edwards) treats a beauty contestant who was injured in a freak "cosmetic" accident; and Chen (Ming-Na) takes care of a terminal patient whose mother is in a state of denial. All this, plus a shoot-out in the ER -- and a mugging in which Kovac (Goran Visnjic) ends up killing his attacker. ~ Hal Erickson, Rovi
