Paris, 1965, the glamorous world of fashion also has its dark sides. Henri Flanelle, the world-famous fashion designer and inventor of the short sheath dress, is found dead. He was stabbed with a heavy tailor's scissors, just one day before the presentation of his latest collection. Only eight people from his inner circle are considered suspects, and they all have something to hide. It quickly becomes clear that behind the dazzling facade of the fashion empire, not everything is as it seems.
