Tired of fending for herself and her mother's penchant for hard-drinking men and barroom drama, 13-year-old Luli (Chloe Moretz) hits the road on her own, heading west to realize her dream of becoming a superstar.
Among her travels she meets Eddie (Eddie Redmayne), a drifter with a chip on his shoulder, and Glenda (Blake Lively), a troubled but spirited woman who takes Luli under her wing. Luli's quick wit, some help from Glenda, the mercurial Eddie, and her colorful daydreams help protect her from the incredibly unpredictable band of characters she encounters on her journey.
