The Cabinet of Dr. Caligari

The Cabinet of Dr. Caligari (German: Das Cabinet des Dr. Caligari) is a 1920 silent film directed by Robert Wiene from a screenplay by Hans Janowitz and Carl Mayer. It is one of the most influential of German Expressionist films.

The deranged Dr. Caligari and his faithful sleepwalking Cesare are connected to a series of murders in a German mountain village.

The narrator, Francis, and his friend Alan visit a carnival in the village where they see Dr. Caligari and the somnambulist Cesare, whom the doctor is displaying as an attraction. Caligari brags that Cesare can answer any question he is asked. When Alan asks Cesare how long he has to live, Cesare tells Alan that he will die before dawn tomorrow.

Francis, along with his betrothed Jane, investigate Caligari and Cesare, which eventually results in Cesare kidnapping Jane. Caligari orders Cesare to kill Jane, but the hypnotized slave refuses after her beauty captivates him. He carries Jane out of her house, leading the townsfolk on a lengthy chase. Cesare falls to his death during the pursuit.

Meanwhile, the police discover a dummy in Cesares cabinet, while Caligari flees.
Francis tracks Caligari to a mental asylum. He is the director! Or is he?
