Inspector Rojas

Captain Rojas arrives in northern Chile from Santiago to investigate the mysterious disappearance of a group of teenage girls in Alto Hospicio.

Intelligence confirmed by the head of the Alto Hospicio police forces Rojas and Carrasco to travel to Tacna, a wild Peruvian city on the border with Chile.

After reviewing all the murders of women in the area, Captain Rojas believes he has found his serial killer''s "Case Zero": a prostitute, whose body appeared on a beach two years ago.

Following the trail of disappearances leads Rojas to 'La Ponderosa' a place in the middle of the desert where private parties are held with prostitutes, many of whom are minors. During his surveillance of La Ponderosa he rescues Ayleen, a young homeless woman.

The case of the Alto Hospicio Psychopath reaches national coverage, but Rojas' investigation into institutional corruption in Hospicio puts him in the sights of several powerful men in the area.

Rojas leaves the hospital after receiving a brutal beating in which Carrasco also secretly participated.

After exposing the corruption and threatening his superior, Rojas continues his investigation without the support of the police. A new clue leads him to investigate a secret within the Avila family.

Rojas is convinced that he has discovered the identity of the psychopath but he has no evidence. He travels to the murderer's hometown, where he discovers the origin of his violent instincts.
