According to a 16th-century Polish legend, an occultist from Kraków sold his soul to the Devil in exchange for magic powers, but later reneged on the deal. The character is said to have been based on a real-life 16th century German nobleman who lived in Kraków and Nuremberg. There were many variations of the folktale over the years and since this film is now considered lost, it's impossible to tell which variation of the legend was used for the plot. But the 1936 sound film remake is said to have followed the story of this film closely, so the two films' storylines must be very similar.[5]
