Directed by UW-Green Bay senior Kiersten Zangl, the play “Sister Mary Ignatius Explains it All for You” will be performed at the Weidner Center’s Jean Weidner Theatre on Dec. 8 and 9 at 7:30 p.m. It is free and open to the public. The play follows the story of Sister Mary Ignatius, who has been teaching children about the glories of Catholicism and the perils of sin and hellfire for years at her church, as she encounters her former pupils. Deeply unsettling, yet absolutely hilarious, “Sister Mary Ignatius Explains It All For You” examines human nature and religion.
