In the year 3040, New York medical student Driscoll Rampart is completing his internship on Rusta, a rural planet which due to it being tidally locked to its primary, is divided into contrasting halves of day and night with the halves separated by a wall. The two sides are involved in a civil war: The day side containing a Victorian-styled colony is at odds with the night containing a medieval kingdom. The differences between the two cultures leaves Rampart in a state of wonder. Rampart arrives from Earth for a six-month stint at the Light Side clinic run by Dr. Akada. Rampart's ambition is to eventually set up a private practice in Manhattan on Park Avenue.
