After receiving an alarming phone call, the nuns order Rose to shovel the driveway "down to the earth" for the abrupt return of Headmaster Gordon.

Gordon arrives with a policeman; as they enter the nuns' cabin, a bloodstain is seen on the wall, and the men react with shock to something offscreen.

She beheads their corpses and brings the heads to the boiler room of the academy, seemingly in an effort to summon the demon she lost years ago.

"[21] Joe Leydon of Variety magazine wrote: "In addition to everything else he does right in "The Blackcoat's Daughter," Perkins plays fair: When you replay the movie in your mind after the final fadeout, you realize that every twist was dutifully presaged, and the final reveal was hidden in plain sight all along.
