Small town teenager Luli (CHLOË GRACE MORETZ) escapes to Las Vegas, leaving behind her alcoholic and abusive parents. Armed with her smarts, a pistol and pocket money, she hitchhikes her way west. Along the way, Luli crosses paths with Eddie (EDDIE REDMAYNE), an unstable rebel with questionable motives and Glenda (BLAKE LIVELY), a cocaine-snorting drifter on the run.
