The tourist postcard appearance of a National Park in the middle of the jungle in Misiones hides a world besieged by ancestral fights and conflicts of interest. Guzmán is a park ranger who tirelessly patrols the reserve in search of poachers. Orlando Venneck is a renowned settler in the area and, like his ancestor, a hunter. Sara Vogel, a committed rural doctor, is married to Guzmán and was previously in a relationship with Venneck. The appearance of a mythical jaguar will divide the small community in which they live and awaken an ancient rivalry between them, making the escalation of violence unstoppable.
