[1] A co-production between Belgium, France and Switzerland, it is an adaptation of Hergé's two-part Tintin adventure The Seven Crystal Balls and Prisoners of the Sun.

Jacques Brel, a fan of the series, contributed two songs to the soundtrack, entitled Chanson de Zorrino and Ode a la Nuit.

Back in Europe, they fall into a deep sleep one by one and only once a day, at the same time, do they wake up for a few minutes and have hallucinations of the Inca god.

His friends Tintin and Haddock follow the track to Peru, up to the mountains through snow and jungle and finally discover the Temple of the Sun, where they are caught.
