Rule-bound Dr. Kayson (Sam Anderson) again incurs the wrath of Lewis (Sherry Stringfield) when he orders the early release of a heart patient named Vennerback (Michael Monks). But when Vennerback is brought back to the ER in critical condition, it is Lewis who is held responsible for the tragedy that follows. Elsewhere, Benton (Eriq La Salle) adopts a somewhat nasty method to stem the constant complaints of his student, Carter (Noah Wyle); and Lewis' pregnant sister, Chloe (Kathleen Wilhoite), announces her intention to move to Texas. ~ Hal Erickson, Rovi
