While a meningitis scare overwhelms the resources and staff of Princeton-Plainsboro Teaching Hospital, House zeros in on a single patient: a 12-year-old whose symptoms are similar to, but not quite right for, meningitis. Cuddy gives them an hour to crack the case before pulling their medical manpower to treat the countless patients taking over the waiting rooms, but when they discover something quite unexpected, House, Foreman and Chase must devise ingenious ways and locations to treat the girl's delicate condition amid the chaos. Meanwhile, House asks Cameron to come back to her job now that Vogler is gone, but she's got a surprising requirement. Cast: Hugh Laurie as Dr. Gregory House; Lisa Edelstein as Dr. Lisa Cuddy; Omar Epps as Dr. Eric Foreman; Robert Sean Leonard as Dr. James Wilson; Jennifer Morrison as Dr. Allison Cameron; Jesse Spencer as Dr. Robert Chase.
