The fourth season of La Caza takes place in the Irati Forest (Navarra). A UCO team is dispatched there when the residents of a small village discover the body of a woman hanging from a tree. This time, Lieutenant Ernesto Selva will be working under the command of Gloria Mencía. What Ernesto doesn’t expect is the arrival of Sara Campos, who, instead of leaving the force after Víctor’s murder, now works as a psychologist in the Criminal Behavior Analysis Unit
of the Civil Guard. But mysterious murders and disappearances continue to occur, and for the first time, the investigators begin to consider the possibility of a serial killer hiding deep within the largest forest in Spain, a place steeped in stories and old legends. A killer whose nature they can’t quite define, and whom some refer to as “The Creature.”
