Among olive groves, a wealthy family welcomes their new governess, Ana Trujillo. There she will meet Jacobo and Sara Ledesma, two motherless siblings who live in fear of the secrets that are hidden in the shadows of the house.

The governess will witness the strange disease that Jacobo suffers from, a disease caused by the return of a past that cries out for justice to be able to rest in peace.

Neither the exorcisms nor the vision of the ghosts that inhabit the house will be a reason for Ana Trujillo to leave the Ledesma family.

The vestige of Casa Matrona Olivares is a must read for all lovers of suspense.
