Netflix released the first trailer for the seven-part series on Wednesday, and already people are comparing it to the streaming company's runaway hit docuseries, "Making a Murderer."

In "The Keepers," which will be available May 19, director Ryan White ("The Case Against 8") tries to find the answer to one of Baltimore's most memorable unsolved mysteries.

Sister Cathy Cesnik, a 26-year-old nun and a beloved Baltimore Catholic schoolteacher, suddenly disappeared in 1969. Her murder case is still unsolved.

Speaking with friends, relatives, journalists, government officials, and Baltimore citizens, White peels back the layers of the mystery to reveal a potential clergy abuse cover-up by the Catholic Church, the police, and the government.
