Mark Greene, that semismart layabout, is back. Venturing to Bunk Bunk Community College to enroll in courses that he hopes might lead to some sort of employment, Mark inexplicably finds himself tossed into the lowest depths of the teaching profession. He's hired as an adjunct to teach English at midnight. Try as he might to impart literature and spark creativity to those in his charge, Mark Greene cannot help but get his own schooling - good and hard.

For Mark Greene stumbles upon a plot in the bowels of the school's Wellness Center to transform the very nature of man. Now he must use all his resources to save humanity from man's oldest and most dangerous desire: to be a god. In this Manichean contest, Mark Greene must defeat the Machiavellian president of Bunk Bunk Community College, President FiFi; a deeply cynical and bitter scientist, the dean of nocturnal studies; an alcoholic, chip-on-his-shoulder politician, Rep. Pat A. Nidge; and, finally, the founder of Planet Pennies, Starbucks' great rival.

Mark, however, has one ace up his sleeve: the love of his life. Her name is Diane, a clerk at the school, enrolled at university, majoring in psychology. Okay, more love than ally, but together they aim to save themselves and all of mankind from man's most ancient and inveterate sin.
