Sister Death

In 1939, in a small town in Spain, a young girl called The Holy Girl is worshiped by the population since she had a vision of Virgin Mary. In 1949, she arrives at a convent that was turned into a school for girls after the Spanish Civil War. Novice Narcisa is welcomed by Sister Julia that introduces her to the Superior Mother that is very happy with her presence. Narcisa will be the replacement for Sister Ines, who left the school, and will be responsible for teaching the girls. In her room, Narcisa finds a cigar box with objects, letters, a pair of scissors and a photograph of Sister Socorro. Then she has dreadful nightmares and mysterious things happen in the room. When the girl Rosa and her sister Elvirita find the pair of scissors in the bathroom during the night, they claim a supernatural event in the bathtub, but Sister Julia does not believe in Rosa and punishes her. Narcisa visits Rosa in her cell and the girl explains that the convent is haunted by the spirit of a girl. What is the mystery of the convent?
