German silent horror directed by Robert Wiene. When a young man is mysteriously murdered after learning from a somnambulist at Dr. Caligari (Werner Krauss)'s side show that he won't live out the night, his friend Francis (Friedrich Feher) is determined to find out the truth behind what happened. With help from his fiancée Jane (Lil Dagover), Francis soon discovers that Dr. Caligari is actually the director of a local insane asylum and is using a deranged patient to pose as his somnambulist in order to commit a series of grisly murders. Springing into action, Francis must put a stop to Dr Caligari's evil scheme before he can claim further victims.
