Ruthless executive Christine takes delight in toying with the innocence of her assistant, Isabelle, 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 the younger woman’s own burgeoning ruthlessness. A slick atmospheric thriller with Kristen Scott Thomas on excellent ‘ice queen' form.
