Inspectors Pacheco and Duarte, on the trail of a psychopath recently released from prison who is hanging around the area, receive a tip-off that he might have been threatening her and had visited her the week before the murder. What seemed an open-and-shut case becomes more complex when signs that Duarte himself might be the chief suspect begiin to appear.
