Pete and Mary find their humdrum life interrupted dramatically by a spirit from the past. All on the surface appears banal and excruciatingly normal, but this ordinary couple must grapple with questions that otherwise they would have conveniently and blithely ignored. The title suggests one of the key questions that Mary and Pete explore. How can an evening—a measure of time—co-exist with eternity? How does time—a measure of past, present and future co-exist with an everlasting now, an eternity? Other questions abound once their comfortable but banal routine explodes with the arrival of these uninvited guests. Do animals possess a spirit? What happens when animals school humans? Is there a hell, and, if so, what is like? What of purgatory and heaven? These and other questions perplex the couple as they spend a most unusual evening of eternity.
