My Nights with Susan, Sandra, Olga and Julie

The biggest mystery about this psycho-sex-drama is why it took five writers (including Harry Kümel, who should have known better) to cobble together dialogue that consists mainly of characters calling out the names in the title. Blond biker stays at farmhouse full of assorted weirdos, namely two murderous nymphets (Sandra and Olga), troubled heroine (Susan), sleeping beauty (Julie) and simpleton hag (Piet) who collects dead bodies and watches everyone spying on each other. Presumably intended as an adult fairytale, it takes itself ludicrously seriously but never overcomes the fundamental problem of so what and who cares.
