Bored and lonely, 15-year-old Hélène decides to pay a visit to her father’s mistress. Within days, she is captivated by Tamara, a Russian émigré whose arts of enchantment include lingering kisses, sudden dismissals, and savage, rapturous reunions. As long as she submits to Tamara, Hélène is permitted to stay near her: reading forbidden novels, meeting Tamara’s bohemian friends, and learning more 'refinements of depravity' than the gossiping matrons of her provincial French town could imagine existed.
