In November 1969, 26-year-old nun, Sister Cathy Cesnik was reported missing in the Baltimore area after disappearing from a Friday night shopping trip.
Her beaten body was discovered two months later in a Baltimore County field. Nearly 45 years later, her murder remains unsolved.
This is the premise for Netflix's latest 'whodunnit' seven-part documentary, The Keepers - the mysterious murder of a nun who knew too much.
Brought to us by the home Making A Murderer and Amanda Knox, Netflix has said The Keepers will cover "the horrific secrets and pain that linger nearly five decades after her death".
