After Brad and Meg move to a detached house in need of major repairs after a fire and decades of neglect, they're happy that cheerful teenage son Tyler behaves normally, for puberty. Young daughter Gina's stories about sometimes evil 'fairies' are equally dismissed, but get worse. Self-appointed handyman warns Iver Hagen them for 'things worse than ghosts' and ever scarier things happen. Ma irrationally believes the house bad yet refuses long to have Gina examined by Dr. Werner, who has a patient Olive obsessed by similar trolls. By the time the pieces are fitted, it may be too late.
