Netflix's newest docuseries is based on an unsolved murder in Baltimore City.
"The Keepers" is a seven-part series documenting the unsolved murder of Sister Catherine Cesnik whose body was found at a garbage dump.
Cesnik taught at Archbishop Keough High School when she went missing on November 7, 1969. Her body was found early the following year.
The trailer hints at police, city and religious official corruption, with some believing Cesnik was killed because she threatened to unearth information about a prostitution ring led by the school's chaplain.
All seven episodes drop on Netflix May 19.
