After their adventures in Ancient Egypt, Luì (Luigi Calagna) and Sofì (Sofia Scalia) would just like to rest, but a new threat looms over Earth. A magical spring hidden in the jungle holds the key to undo all the world’s spells but, if contaminated, could turn Earth into a barren, lifeless desert. Viperiana has discovered this and with the help of her faithful servant Serpe has already begun mixing witch potions into the spring that turns the water purple; it will only take a few days for everything to be irreversibly poisoned. A struggle against time begins for Luì and Sofì, who together with their sidekick Pongo and accompanied by their guide Serenino and Tara, daughter of the Pesantosi tribal chief, will have to decipher the map that will lead them to the magic spring and foil Viperiana’s evil plan. But they must be careful, for an unexpected enemy lurks among them!
