Doctor Mazali (Rafael Bertrand) makes a pact with his dying colleague, Dr Aldama (Antonio Raxel), in order to learn the secrets of the afterlife. Instead, the spirit of Aldama exerts a supernatural influence on him from beyond the grave, summoning his daughter, Patricia (Mapita Cortés), to Mazali’s asylum, where a series of horrific events ensue.
