Ten-year old Jo spends her days along the Shenandoah River - fishing, scrapping for metal, surviving - with her best friend Selma. But, when her abusive junkie stepdad dies, Jo decides to dump the body, steal the car, and set off across the country (Selma in tow) in search of her real dad - the legendary Jonny Alvaraz, Last of the Southern Gentlemen and a once-popular folk singer now living in Los Angeles.
