After being wrongfully imprisoned due to a judicial error, Constance Mayer decides to try a new career path. At the age of fifty, the former farmer earns a law degree and moves to Marseille to clerk for the highly demanding judge Frédéric Filiponi. Constance is a bubbly and energetic woman who doesn't hold back, bringing a fresh perspective to the cases the duo takes on. She draws the ire of her colleagues at the courthouse, who think she has a chip on her shoulder. But Constance's empathetic nature and nontraditional approach turn the clerkship into a mutual learning experience, as her novel investigation methods and humane approach force Filiponi to step outside his comfort zone.
