The Ages of Lulu.

Fifteen-year-old Lulu has never known any affection from her family. But when she goes to a rock concert with Pablo, a friend of the family, he introduces Lulu to her first sexual experience. Years later, Pablo and Lulu have married; Pablo has created a sheltered, private world for Lulu, into which nothing intrudes. However, Lulu tires of her cloistered existence, and begins hanging out in shady bars, looking for vicarious thrills and danger.
