The seven-part documentary series “The Keepers” follows the 1969 unsolved murder case of Catherine Cesnik, a 26-year-old nun and teacher in Baltimore. The Netflix series poses a theory: Sister Cathy died because she was about to expose sexual abuse at Archbishop Keough High School, particularly at the hands of the chaplain there, Father Joseph Maskel. “The Keepers” also looks at the Catholic Church’s close ties with Baltimore’s law enforcement, and a possible cover-up.
