Plot: The Inca worshiped both a creator god and the sun, moon and stars. In this episode, host Christy Kenneally travels to the Peruvian Andes to explore the remnants of Inca civilization: the city of Pisac, which like all Inca cities was designed in the shape of a sacred animal; Cajamarca, where the Inca leader Atahualpa was murdered by the Spaniards; and the sacred mountaintop city of Machu Picchu
