Confident second-year resident Pratt wants to prove his abilities when he works the graveyard shift (11 p.m. to 7 a.m.), but his heroics sometimes backfire. Pratt shows contempt for a man, Ed Gamble (Paul Cassell), who presents no symptoms of disease but temporarily loses his speech. As Weaver decries the "incompetence" of her staff, she also makes a grievous error. A screaming man with a broken leg waits several hours for treatment, and Neela deals with a little girl who arrives with her beloved grandmother whose status is DNR ("do not resuscitate"). Meanwhile, Abby is desperate for money and credit. Later, she meets both Kovac and his new girlfriend. And Corday begins to appreciate Dr. Dorset (recurring guest star Bruno Campos).
