Rottweiler

Dante is arrested for illegally entering Spain and is imprisoned in Kufard's prison. During an escape attempt, he is forced to kill a prison guard, triggering a dangerous hunt by the warden's cybernetically enhanced Rottweiler.

Dante escapes from prison but is immediately pursued by the cybernetic Rottweiler. The dog is relentless, tracking him through the prison outskirts and countryside.

On the run, Dante is exhausted and begins to hallucinate memories of his and Ula's arrest. The cyborg dog closes in, turning the chase into a claustrophobic ordeal.

Dante stumbles onto a small farm and is held at gunpoint by Alyah, who is accompanied by her young daughter Esperanza. She demands his identity and studies him with suspicion.

Inside Alyah's house, Dante explains that he traveled without papers and needs help to get to Puerto Angel. Alyah binds his wound and tests his trust, warning that his future is precarious.

Alyah strips and seduces Dante, telling him that he might belong to anyone who can pay. She reveals she once worked for Kufard in Puerto Angel and explains Esperanza is her beacon of hope for a better life.

Esperanza has seen the Rottweiler and tries to warn Alyah, but her cautions are dismissed. The dog then begins killing the farm's dogs, escalating the threat to the household.

Alyah attempts to defend the group by blasting the Rottweiler, but the beast overpowers the weapon and destroys the shotgun. The dog then kills Alyah as she locks Esperanza in a storage cellar.

Dante frees Esperanza and the two flee toward safety, slipping into a semi trailer to escape the farm. The Rottweiler persists, chasing them along the yard and road.

The dog clings to the semi-trailer; a driver on the highway is killed when she investigates the suspicious noise. Dante and Esperanza inch closer to Puerto Angel while staying ahead of the dog.

Arriving in Puerto Angel, Dante cannot find Ula at the brothel and recalls that Kufard had let his dog loose on her, leading to her death. This memory fuels his resolve to confront Kufard.

Dante confronts Kufard in a brutal struggle as the Rottweiler closes in. They fight amid the burning wreckage of Kufard's helicopter, and both Kufard and the Rottweiler are killed. The morning after, firemen discover the skeletal remains of Dante, Ula, and the Rottweiler on the beach.
