Benavídez, an art teacher and son of a famous painter, argues with his wife and, distraught, leaves with a suitcase to spend the night at his psychiatrist’s house. That night, Dr. Corrales looks inside the suitcase, finds his patient’s work, and decides to lock him inside the house. In the mansion of the doctor -who is both physician and art collector-Benavídez discovers a dark secret: a boarding school of artists subjected to a treatment designed by the psychiatrist to expand their creative spectrum and profit from the works produced there.
