The protective Dr. Pratt is overwhelmed when his mentally challenged roommate Leon leads him to treat a gravely wounded suspect who was responsible for a robbery and holdup -- which also involved the easily duped Leon -- while Dr. Carter stuns Abby when he decides to go to Africa where the medical needs are greatest. Elsewhere, Carter attends to the sickly Dr. McNulty, the curmudgeon he recently met who runs a storefront medical clinic; the emotionally fragile Dr. Romano teeters on the brink of disaster and receives negative news regarding his recovery; Dr. Kovac intends to carry out a threat made to Dr. Weaver, who also re-encounters a grateful alderman who returns bearing financial gifts; and a skilled and bold doctor makes a pass at a shocked Dr. Corday.
