In a natural reserve in the jungle of Misiones, Ismael Guzmán, a busy ranger, patrols daily the mountain searching for poachers. Orlando Venneck is a settler of European origin, owner of a farm, and a hunter. Both venerate the mountain in their own way, but the use they make of it puts them in opposite places. Sara Voguel, a committed rural doctor married to Guzman and Venneck’s ex fiancée will be the center of the dispute.
