Mascara plot
Bert Sanders is a police commissioner who attends the premiere of Christoph von Gluck's 'Orfeo ed Euridice' with his sister Gaby. There he meets Chris Brine, the designer of Euridice's costume. Gaby and Chris are attracted to each other. Bert visits Chris to borrow Eurydice's dress for a party. Assuming that Bert is Gaby's girlfriend and that it is for her, Chris agrees on the condition that he will put the dress on her. He has to go to a subterranean nightclub for this. Once there, he ends up in a world full of hermaphrodites, transvestites and above all a lot of sex. This is also the beginning of a series of murders.
