Where has Samba the cat gone? That is what Pilar and Breno have to find out! They quickly enter the magic net and... off they go on a breathtaking adventure. Up in the mountains of Peru, they will explore the secrets of Machu Picchu, the Sacred City, and will try to prevent that the young Yma, chosen by the Sun God, stays there forever.
While getting to know the traditions and legends of the Inca civilization, Pilar, Breno, and Samba live through unforgettable and dangerous moments - they walk along the banks of the Urubamba River, face the mighty Supreme Priest, hide in stone temples, delight themselves with corn and quinoa, and learn a lot of words from the Quechua language.
