'Late Nite Catechism' takes audience members back—sometimes nostalgically, sometimes fearfully—to the children they once were. The irrepressible Sister teaches an adult catechism class to a roomful of “students.” Over the course of the play, Sister goes from benevolent instructor, rewarding the audience for correct answers with glow-in-the-dark rosaries and laminated saint cards, to authoritative drill sergeant. These abrupt mood swings are bound to strike a resonant chord with anyone who survived the ups and downs of going to Sunday school.
