About the title
We first learn of some rather frightening events faced by the local residents of Madrid, Spain. It is to this city that a young police officer named David, gifted with sharp instinct and intuition, is sent. Duty requires him to track down, within a strict deadline, the suspected killer behind these atrocities. He must launch an investigation that brings him into contact with a young man named Jorge, who works for an odd comic book seller. Since all the victims of the bloody maniac turn out to be connected by nothing but the appearance of certain comic-book stories, the protagonists are forced to join forces to identify the culprit by any means necessary, risking their lives, and bring him to justice.
