As with many films from the pre-sound era, deft plotting falls near the end of the list of "L'Inhumaine's" recommendable qualities. Claire (opera singer Georgette Leblanc) functions as a distaff forerunner of the Most Interesting Man in the World. She's a renowned diva and bon vivant who hosts decadent parties in her lavish proto-modernist mansion, alternately revving up and icing the many suitors who swarm her. ("L'Inhumaine" translates as "The Inhuman Woman.") One of those suitors, earnest scientist Einar (Jaque Catelain), is so distraught by her hot-and-cold act that he plunges his roadster off a cliff. At first, Claire doesn't care, but asked to identify his body, she discovers her true tender feelings—and (surprise!) Einar reveals that he faked his own death. This leads to hard feelings from romantic rival Djorah (Philippe Hériat, acting in swarthface), assassination by asp, a "Frankenstein" plot bite, and more.
