The Keepers is a seven-episode American documentary web series that explores the unsolved murder of nun Catherine Cesnik in 1969. Cesnik taught English and drama at Baltimore's all-girls Archbishop Keough High School, and her former students believe that there was a cover-up by authorities after she suspected that a priest at the high school, A. Joseph Maskell, was guilty of sexually abusing students. The series was directed by Ryan White and released on Netflix in 2017.
