As the rest of the school gets ready for the senior prom, Toffee continues to wear black clothing in mourning for Jonny ("Good As It Gets").

He states that it has been "a very long time" and the two have a cryptic conversation, in which Miss Strict is defensive and angry for an unknown reason.

Miss Strict retaliates by canceling the pep squad; not slowed by her tactics, they begin to disobey the dress code.

During a commercial break, he asks for the number to Our Lady of Divine Masochism, a Catholic orphanage, for unspecified reasons.

It is revealed that they were lovers in high school, with a very physical relationship - the last time they were together, Miss Strict reminds him, was in the back seat of his father's Studebaker.

Before she can do so, Eddie Flagrante appears in order to confront Miss Strict about her secrets and her hostility towards Jonny, but she refuses to explain herself ("The Lid's Been Blown").

On the evening of her own prom, she and Flagrante drove around before stopping off an old highway and slept together, resulting in Miss Strict becoming pregnant.

Flagrante, who had investigated the orphanage, reveals that Jonny is their long-lost son and proposes to Miss Strict.

Overjoyed, Miss Strict allows the prom to continue and permits Jonny to come back to school.

The students reflect on how their realities are so much different than their dreams, but still life's worth living, and Toffee and Jonny have one more dance before the curtain drops ("Zombie Prom").

The cast of the 1996 Off-Broadway Production was as follows:[2] Eddie Flagrante – Richard Muenz Delilah Strict – Karen Murphey Jonny Warner – Richard Roland Toffee – Jessica-Snow Wilson Coco – Cathy Trien Ginger – Natalie Toro Candy – Rebecca Rich Joey – Marc Lovci Jake – Stephen Bienskie Josh – Jeff Skowron Swings – Ronit Mitzner, DJ Salisbury Reviews of the original Off-Broadway production were generally mixed to negative, with critics praising the cast and the show's humor while also criticizing the book.

In his review for The New York Times, critic Ben Brantley wrote: "Zombie Prom, ... is itself like a model high school student: it's genial and hard working, and it doesn't embarrass you.

... [the show] relies heavily on this sort of straight-faced pairing of Eisenhower-era perkiness with the nuclear nightmare sensibility of horror movies of the same time.

It is essentially a one-joke show, very much in need of more bite than the director Philip William McKinley seems willing to give it, that would have worked better as an extended sketch in a revue.
