It's 1944 and the Allies have invaded Nazi-held Europe. In Spain, a troop of soldiers are sent to a remote forest to flush out the rebels. They are led by Capitan Vidal, a murdering sadist, and with him are his new wife Carmen and her daughter from a previous marriage, 11-year-old Ofelia. Ofelia witnesses her stepfather's sadistic brutality and is drawn into Pan's Labyrinth, a magical world of mythical beings.
