The animated film is based on Neil Gaiman's best-selling book, which is the story of a young girl who unlocks a mysterious door in her new home and enters into an adventure in a parallel reality. On the surface, this other world eerily mimics her own life - though much more fantastical. In it, Coraline encounters such off-kilter inhabitants as the morbidly funny Miss Forcible and Miss Spink, and a counterfeit mother - who attempts to keep her. Ultimately, Coraline must count on her resourcefulness, determination, and bravery to get back home.
