Based on French writer Colette's 1923 novel, Le Blé en herbe focuses on the changing relationship between childhood friends Vinca and Phillipe. Both are on the verge of adulthood and beginning to recognize romantic feelings for one another when Phillipe meets a lascivious, wealthy older woman named Madam Dellaray. He is torn between his innocent but restricting affection for Vinca and satisfaction of his impatient lust for the new and mature world Madam Dellaray offers.
