Tideland(2006)

Jeliza-Rose is a young child in a very unusual situation - both parents are junkies. When her mother dies, she embarks on a strange journey with her father, Noah, a rock'n roll musician well past his time. Jeliza-Rose escapes the vast loneliness of her new home into the fantasy world that exists in her imagination. In this world fireflies have names, bog-men awaken at dusk, and squirrels talk. The heads of four dolls, long since separated from their bodies, keep her company: Mustique, Baby Blonde, Glitter Gal and Sateen Lips, until she meets Dickens, a mentally damaged young man with the mind of a ten-year-old. Dressed in a wet suit and speedo, he spends his days hiding out in junk heaped wig-wam turned submarine, waiting to catch the monster shark that inhabits the railway tracks. Then there's his older sister Dell, a tall ghost-like figure dressed in black who hides behind a beekeeper's mesh hood.
