Dedo de Moça (2007)

Wiley Roth finds a severed human finger in his kitchen one night. Understandably freaked out, in a search across Los Angeles that brings them in contact with psychics, ineffectual police, crooked taxidermists, mysterious neighbors who might be on drugs, and a nine-fingered woman named Cheryl who might, improbably, end up being the girl of his dreams.
