Mattéo Fabrizzi, 29, famous couturier, is preparing his new collection, the third of his career, which will secure his place in haute couture. With less than two days left, he is unhappy with the designs, in particular with the opening dress, prepared by stylist Jeanne Mercoeur. Enraged, he dismisses all his employees until the next day; later on, he collapses dead near the catwalk. Investigators discover that he was wearing a bulletproof vest and the coroner confirms death due to internal bleeding. On the private ground, Alice and Marquand disagree on the situation with Lucie, the commander's supposed daughter, and her mother Rachel Fronsac.
