From a town of steelworkers in the wounded heart of postwar Europe to the lavish glamour of the jet set, Hit the Road, granny! tells an eccentric and incredible life story set in the world of international fashion. Born in a French village from a family of poor Italian immigrants, Delia Ubaldi grew up to build a successful business empire in the fashion industry, conquering first Europe, then the U.S. with her collections of Italian clothes. In the early 1980s, the cult film American Gigolò shows Richard Gere shopping in Delia’s luxury fashion store in Beverly Hills. Today, her grandson goes visiting her in a humble rented apartment in rural Germany. Was she an actual millionaire? Why all of a sudden, she stopped being wealthy? Where has her fortune gone? Part road movie, part family saga, this documentary tells the story of stubborn and controversial woman, passionate yet problematic. In a constant conflict between private and public life, her ambition always clashed with her family’s expectations and her duties as a mother. Now in her 90s, Delia retraces the most important episodes and encounters of her life, providing a unique angle on the changes in lifestyle and society through the last five decades.
