Wanderlust is the story of Audrey Driscoll. Orphaned young, Audrey has grown up caring for her eccentric millionaire grandfather and her demanding younger sister, Annabelle, who assume she will always be there for them. Sheltered yet restless, responsible beyond her years yet hungering for experience, Audrey is hopelessly bound until she herself makes the daring decision to leave. As the 1930s unfold, alone, camera in hand, she will shock friends and outrage family as she plunges headlong into the wider world.
