We thus find our friends in the land of the Incas in order to find Sunflower. The Peruvians are very distrustful of them until Tintin help small Zorino. This then takes them to the distant Sun Temple where sunflower is being held. The expedition proved to be very long and difficult. It is obviously not as simple to reach to the temple. After many adventures, our friends manage to find a hidden entrance, but they are quickly captured by the descendants of the Incas in person! It took all the ingenuity of Tintin (and that's saying something!) And also a lot of luck to get out of this situation and stop the curse.
