The mountain worlds of the Caucasus mark the border between Europe and Asia. The film shows the species and landscape diversity of the lesser Caucasus in Armenia, Georgia and Azerbaijan. Shielded from the main ridge of the Greater Caucasus, a thermophilic flora and fauna has been able to develop there. For the first time, the land bridge between Europe and Persia is portrayed comprehensively: From the mountains of Dagestan to the canyons of the Caspian Basin and to biblical Mount Ararat.
