It's the night of the Jellicle Ball. The cat clan has gathered for the annual event at which the revered elder Old Deuteronomy chooses the most deserving cat to ascend with him for a heavenly reward. The cats have gathered, and one by one, we learn about their personalities, exactly as T. S. Eliot portrayed them in his book of poems. Jennyanydots, Cassandra, Bombalurina, and Jellylorum are the first to strut their stuff. They welcome Rum Turn Tugger, a rock-star-idol type of cat, creating just the right mood for the arrival of Grizabella, the Glamour Cat. She is an aging beauty who has roamed some of the lowest alleys.

The younger felines mock and avoid her. Bustopher Jones, mature and well-rounded, catches everyone's eye with his natty clothes and well-groomed look. Mungojerrie and Rumple teazer, two mischievous, fun-loving cats, provide a light moment before Old Deuteronomy arrives and sets a more serious tone for the ball. Barred from the festivities, Grizabella reflects on her memory of happier times and the new life that could be ahead. Also on the sidelines, Gus the Theatre Cat finds fault with the lack of dedication he perceives in today's actors and reminisces about some of his finest roles. In Skimbleshanks the Railway Cat, we find great pride and commitment in doing the rela tively small job of keeping a single train on schedule. Macavity, the "fiend in feline shape, a monster of depravity," is talked about in hushed voices. "Was there ever a cat so clever as magical Mr. Mistoffelees?" Yes, and much to the delight of all he bursts upon the scene. Still it is Grizabella that demonstrates the greatest depth of character and need. She is chosen to accompany Old Deuteronomy on this year's accension "up, up, up, past the Russell Hotel. Up, up, up to the Heaviside layer."

Before their departure Old Deuteronomy summarizes Eliot's lifelong passion for paralleling catlike names and attributes to people he had observed;

"You've heard of several kinds of cat, and my opinion now is that, you should need no interpreter, to understand our character. You've learned enough to take the view, that cats are very much like you."
