Mr. Burns, a Post-Electric Play is a three-act play that explores the evolution of a pop culture artifact, The Simpsons, into a new mythology after a societal collapse. In Act I, survivors gather around a campfire to reconstruct The Simpsons episode "Cape Feare" from memory. The play then jumps seven years ahead, where this memory has become a live performance for a community. The final act takes place 75 years later, showing how the show has been transformed into an epic, musical, and operatic morality play that blends pop culture with Greek tragedy and other art forms.

Quincy enters in the second act as one of the survivors who is trying to rebuild society after a global catastrophe. She is a member of the traveling theater troupe that re-enacts and performs episodes of The Simpsons to entertain and educate younger generations about the past. Quincy is defined by her assertive and sometimes inflexible nature, and her actions are driven by her strong-willed personality and clear ideas about how things should be done.
