A group of young adventurers-Jean Luc, Aylén, Ludovico, Martín, and Serena-returns to the remote National Park in the Yungas, near the Andes Mountains, where they got lost ten years ago. Now, eager to relive that experience and explore the mysteries of the place, they embark on an expedition with Kovacs, a former park ranger, and Lazslo, a Hungarian hermit living in the forest. Their journey leads them to the discovery of a radioactive monolith, a meteorite that wiped out an ancient civilization and altered the local flora and fauna. In the heart of the jungle, the young adventurers encounter the forest guardians, enigmatic beings who communicate telepathically with Lazslo. Meanwhile, Serena survives a plane crash and hides in the jungle, fleeing from drug traffickers and finding refuge in an abandoned cabin. Guided by mysterious little beings, Serena explores the jungle and uncovers its secrets. The group, along with Lazslo, tirelessly searches for Serena, facing dangers and discovering the ruins of "The Ancients." Together, they must unravel the jungle's secrets and confront the drug traffickers in a story filled with exoticism, mystery, and magic
