Incubus

Demons in the form of lovely young women lead dishonorable men to their deaths. One particularly beautiful demon meets and falls in love with an honorable young soldier (William Shatner). Her older sister (also a demon) is outraged and conjures (in a stirring scene) their fierce brother, who brutalizes Shatner's sister. A haunting, breathtakingly photographed tale of good and evil, love and revenge, INCUBUS also has the odd distinction of being filmed entirely in Esperanto, the language created in 1887 to facilitate easy communication between people of different cultures. Director Leslie Stevens was a frequent contributor to the original OUTER LIMITS television series.
