Sister Mary Explains It All (2001)

When it comes to sin... she's hell on wheels

Near Christmas, four former students of Sister Mary Ignatius drop in at a holiday event at the school where the Roman Catholic nun has taught for many years. Now adults, the students have decided to tell Sister Mary that her rigid classroom lessons and demeanor left them emotionally wounded. Sister Mary tries to maintain her composure, but as the ex-students keep at it, the evening takes a stunning turn.
