She argues with her mother, Sue-Ann, who is about to marry a Mormon, Ray, and amidst the chaos she befriends Clarke Walters, a shy, gay classmate. Together, they flee in a car owned by Clarke's homophobic father, Joseph, and embark on a road trip to Fresno, where Danielle expects to find her birth father, Danny Briggs. Meanwhile, Sue-Ann and Clarke's mother, Peggy, chase after them.
