Thir13en Ghosts: Arthur and his two children inherit his uncle's estate: a glass house that serves as a prison to twelve ghosts. When the family, accompanied by a nanny and an attorney, enter the house they find themselves trapped inside an evil machine 'designed by the Devil and powered by the dead' to open the Eye of Hell. Aided by a ghost hunter and his rival, a ghost rights activist out to set the ghosts free, the group must do what they can to get out of the house alive.
