Who killed Sister Cathy? That’s the question on everyone’s mind in the first trailer for Netflix‘s “The Keepers,” a new documentary film about the 1969 murder of Cathy Cesnik, a nun and English teacher at Keough High School in Baltimore, Maryland. The mysterious nature of Cesnik’s death — and the institutional corruption that led to her tragic end — are the focus of Ryan White‘s (“Serena,” “The Case Against 8“) newest film, already being pitched by Netflix as 2015’s answer to their hit series “Making A Murderer.”

Those who want to spoil themselves on the series — if it’s possible to spoil yourself on historical events, I suppose — would do well to read “Buried in Baltimore: The Mysterious Murder of a Nun Who Knew Too Much,” the longform report published by The Huffington Post in 2015 that explores the city and some of the events surrounding Cesnik’s murder. The rest of us? We can wait a month until “The Keepers” hits Netflix and see the secrets hidden by this not-so-small town.

Here’s the full description of “The Keepers”:

Through interviews with dozens of friends, relatives, journalists, government officials and Baltimore citizens determined to uncover the truth, White pieces together a story that goes beyond the death of a beloved Catholic schoolteacher to encompass clergy abuse, repressed memories and government and religious institutions that he says “at best, dropped the ball over the last 45 years — and, at worst, covered it up.

“The Keepers” will hit Netflix on May 19, 2017.
