The Enigma of Kaspar Hauser

A young man named Kaspar Hauser suddenly appears in Nuremberg in 1828, barely able to talk or walk, and bearing a strange note.
The film follows Kaspar Hauser (Bruno S.), who lived the first seventeen years of his life chained in a tiny cellar with only a toy horse to occupy his time, devoid of all human contact except for a man who wears a black overcoat and top hat who feeds him.
