A nun's 25th teaching anniversary at Christmas is celebrated by four former students returning at her invitation and they plan to replay their unique Christmas story pageant as they did in 1959. The audience is treated to a "lecture" by Sister Mary Ignatius, she answers questions from the audience, the revised pageant is performed, the students' lives are revealed to the sister and one student tries to kill the nun. Defly taking the gun away, the nun kills the former student in an act of self-defense, but then kills a second former student because he is gay but just recently confessed that day and so he will go to heaven.
