Mazeppa is the history of a passion. The exclusive passion which attaches two men to horses. The one runs out wanting to paint them in movement, it is Théodore Géricault, famous artist of the XIXth century. Other one is proud of dominating them completely, it is Franconi, the rider who manages an itinerant troop of riders and who we call “master”. What gathers these two men, it is the will of master to teach Géricault what is really a horse, it is the appetite which Géricault has to learn. A movie beautiful as a fireworks which celebrates the union crowned of the man and the horse.
