Klinger takes his civil service exam on less than 12 hours' notice, Potter tries to get D'Angelo, who'd rather buy a new canopy, to get a new autoclave, and Mulcahy deals with a patient who thinks God is trying to kill him.

During the night shift at the hospital, Pfeiffer deals with fatigue and overwork, Mulcahy helps a patient see his son, and Klinger searches for missing mattresses, while Potter tries to get back home to a fancy dinner with his wife.
