In 1954, the young psychiatrist Germán Velázquez returned to Spain to work in the women's asylum in Ciempozuelos, south of Madrid. After going into exile in 1939, he lived in Switzerland for fifteen years, welcomed by Dr. Goldstein's family. In Ciempozuelos, Germán is reunited with Aurora Rodríguez Carballeira, a paranoid, highly intelligent parricide who fascinated him at the age of thirteen, and meets a nursing assistant, María Castejón, whom Doña Aurora taught to read and write when she was a child.
