A rainy night. Luz, a young taxi driver, stumbles into the brightly lit entrance of a run-down police station. She is confused and numb. Nora talks to Dr. Rossini, a police psychiatrist, in a seductive way at a bar. Nora tells the Doctor about Luz, a girl she went to school with in Chile, and how she used to act out. Nora is controlled by a demon that loves Luz and wants to be with her.
