Gérald Laroche

A group of criminals try to harness the dark magic in a serial killer's diary to escape from prison.

Ruthless executive Christine (Kristen Scott Thomas) takes delight in toying with the innocence of her assistant, Isabelle (Ludivine Sagnier), passing her young protege's ideas on as her own. Confident of her control over Isabelle, Christine leads her into a confusing, perverse game of seduction and domination, but ultimately underestimates Isabelle's ambition and cunning, leading to an all-out boardroom battle with deadly consequences.
