Frédérique (Isabelle Renauld), an independent, twice-divorced optician and mother of two, enters into an intense, passionate relationship with Christophe (Francis Renaud), a younger, emotionally volatile man. What begins as an intoxicating physical affair quickly deteriorates into a deeply codependent and toxic power struggle. Christophe's overwhelming insecurities, jealousy, and obsession with controlling Frédérique drive her to grow increasingly distant and contemptuous, yet she remains emotionally tethered to the destructive dynamic. Framed around the fatal aftermath of Christophe's violent breakdown, the narrative explores the fine line between passionate attachment and destructive hostility.
