A young girl (Fanning) walks through a secret door in her new home and discovers an alternate version of her life. On the surface, this parallel reality is eerily similar to her real life - only much better. But when this wondrously off-kilter, fantastical adventure turns dangerous, and her counterfeit parents try to keep her forever, Coraline must count on her resourcefulness, determination, and bravery to get back home - and save her family.
