From the description:
"In 1606, the city of Prague shines as a golden mecca of art and culture carefully cultivated by Emperor Rudolf II. But the emperor hides an ugly secret: His bastard son, Don Julius, is afflicted with a madness that pushes the young prince to unspeakable depravity. Desperate to stem his son’s growing number of scandals, the emperor exiles Don Julius to a remote corner of Bohemia where the young man is placed in the care of a bloodletter named Pichler. The bloodletter’s task: cure Don Julius of his madness by purging the vicious humors coursing through his veins.
When Pichler brings his daughter Marketa to assist him, she becomes the object of Don Julius’s frenzied—and dangerous—obsession."
