Scripted by Jean Cocteau, who was apparently present during filming, this stylised updating of the Tristan and Isolde myth was made during the German Occupation of WWII and has remained neglected largely because it was accused of being collaborationist by post-war critics. Jean Marais and Madeline Sologne are the doomed lovers, poisoned by the malevolent dwarf, Achille. Patrice brings Nathalie to the chateau of his recently widowed friend Mark in the hope that they will marry. However Patrice and Nathalie fall hopelessly in love as a result of a love potion. From the moment she arrives, Nathalie senses the danger at her new home, but is powerless to avoid her fate and slowly but inexorably the tragedy unfolds.
