The film is based on true events leading up to the historical 2013 resignation of Benedict XVI. After succeeding John Paul II, and serving as Pope for eight years, Joseph Ratzinger shocked the world by becoming the first Pope to voluntarily resign in over 600 years. In light of moral and ethical upheavals in the Catholic Church, and the unique challenges of the 21st century, Ratzinger's cited reason of declining health raises more questions than it answers.
