Imprisoned Soul (German: Gefangene Seele) is a German silent drama film of 1917 directed by Rudolf Biebrach and starring Henny Porten, Paul Bildt, and Curt Goetz. A young woman, Violetta, falls under the hypnotic power of the villainous Baron von Groot. A young physician tries to rescue her from his clutches. She is finally released from Groot's power when he is found shot dead. The film's theme of hypnotic domination is very similar to that of The Cabinet of Dr. Caligari (1919) which the screenwriter Weine was to direct two years later.
