Tideland (2005)

Pre-teen Jeliza-Rose's parents are hopeless drug addicts. When pa, rocker Noah, finds ma's OD'd, he fears to be charged with homicide and takes Jeliza along to his ma's place, in a desolate country region. With Noah dead in his chair, the girl mentally transfers to a fantasy world she and her doll heads enter magically. Jeliza's adventures also star the crazy locals, notably Dell, and Dell's grown but intellectually disabled brother Dickens.
