A killer has found a way to kill women without committing the crime. He gets them to fall in love with him, like Isolde falls for Tristan in the epic poem, and then he leaves them. Heartbroken they choose suicide, just like Isolde.
The Blue Villa is a seedy bordello on a Mediterranean island where the villages are frightened by the ghost-like return of a young man, who mysteriously disappeared after the killing of a young Eurasian woman.
