Lula Viramontes aches to one day become someone whom no one can ignore: a daring ringleader in a Mexican traveling circus. But between working the grape harvest in Delano, California, with her older siblings under dangerous conditions; taking care of her younger siblings and Mama, who has mysteriously fallen ill; and doing everything she can to avoid Papa's volatile temper, it's hard to hold on to those dreams. Then she meets Dolores Huerta, Larry Itliong, and other labor rights activists and realizes she may need to raise her voice sooner rather than later: Farmworkers are striking for better treatment and wages, and whether Lula's family joins them or not will determine their future.
