At a student-led outing to a country inn, Balduin encounters the figure Scapinelli who offers him money "for very low interest."

After the match, the viewer sees Scapinelli on a cliffside, watching a young woman (later revealed to be Margit, the daughter of a count) on horseback who is participating in a boar-hunt.

As a reward, she gives Balduin a crucifix which has fallen from her neck and later he receives an invitation to the house of her father, Count Schwarzenberg.

His happiness does not last long, because his reflection, free of the mirror, runs amok, causing havoc around town, which is blamed on Balduin.

[citation needed] Among the crew was designer Hermann Warm; cinematographer Günther Krampf; and the actors Werner Krauss, Conrad Veidt, Dagny Servaes,[5] Leni Riefenstahl[5] and Elizza La Porta.

The film featured impressive special effects for its time, especially the finale in which the lead character is forced to confront his other half, with seamlessly executed split screen technology.
