Rosaura, a devout religious woman, lives in a fishing village with her sister María who stopped believing in God since her jealous husband was murdered. Even though Rosaura is wanted by the fisherman José, she rejects him. Pedro, a horseman, arrives at her place and begins to harass María until he manages to possess her. The man is a criminal who usually cheats with fishermen and hurts those who dare to confront him with his ax. When the evildoer tries to abuse Rosaura, José, the fisherman, does what is necessary to avenge the insult. Furthermore, other men are already looking for Pedro.
