After a fall from a horse, a 20th-century nobleman remains convinced that he is Henry IV, Holy Roman Emperor in the 11th century. For more than twenty years, his family indulge his madness, until his nephew and former companions decide to cure him once and for all. But their attempt reveals a reality far more destabilizing and tragic than they could have imagined.
