Fifteen-year-old Lulu (Francesca Neri) has a crush on Pablo (Oscar Ladoire), the best friend of her older brother, and loses her virginity to him. Years later, as an adult, they meet again in Madrid, where Pablo introduces her to a dangerous world of uninhibited desire. Based on the controversial novel by Almudena Grandes, The Ages of Lulu is a provocative tale of sexual awakening and exploration.
