After losing her virginity, 17-year-old budding beauty Isabelle (Vacth) takes up a secret life as a call girl, meeting older gentleman clients for erotic hotel room trysts. But throughout her sexual escapes Isabelle remains curiously aloof, showing little interest in the encounters themselves or the money she makes from them. What then does Isabelle hope to gain by offering her body up to the whims of strangers? A sleek and sexy coming-of-age drama, Young And Beautiful heralds the arrival of a new talent as guided by the masterful hand of one of cinema's most assured artists.
