Return to House on Haunted Hill is a 2007 American horror film and the sequel to the 1999 film House on Haunted Hill. Directed by Víctor Garcia and written by William Massa, the film stars Amanda Righetti, Tom Riley, Cerina Vincent and Erik Palladino. The film follows Ariel Wolfe — younger sister of Sara Wolfe, a character from the previous film — being forced by a group of people to search for a mysterious idol hidden inside an abandoned and haunted psychiatric asylum. The film was released straight-to-video on October 16, 2007 on DVD, Blu-ray, and HD DVD formats. Plot Ariel Wolfe is the sister of Sara Wolfe, a survivor of a birthday event eight years ago in the Vannacutt Psychiatric Institute for the Criminally Insane, which at that time had been first abandoned and later converted into a private residence— but has since been abandoned yet again. In the 1930s, the asylum was overseen by the sadistic psychiatrist Dr. Richard B. Vannacutt. Sara claimed that ghosts of the house residents killed the party guests, and later commits suicide. Ariel and her friend Paul are kidnapped by an art dealer, Desmond Niles. Ariel realises that Sara didn't commit suicide: Desmond killed her. Desmond forces Ariel to help him find an artifact located inside the old Vannacutt Psychiatric Institute, a figurine of the demon Baphomet. Inside the building, they encounter Dr. Richard Hammer and his assistants Kyle and Michelle. Ariel explains that the building has been rigged to keep everyone inside for at least 12 hours. The group splits up to search for the idol. Desmond's henchmen are killed by the inmate ghosts, having visions of the patients there suffering the same deaths as them. A ghost shows Ariel the depravity the inmates suffered under Dr. Vannacutt. These images reveal that Vannacutt was driven mad by the idol, and performed experiments on the mentally ill. The inmates led a revolt against Vannacutt, during which the sanatorium burned down. (The audience is shown footage from the 1999 film House on Haunted Hill.) The deaths in the previous film were assumed to be caused by the ghosts. But now Ariel is shown that the dead are actually forced by the idol to do Vannacutt's bidding and did not willingly kill. Although the 12 hours are up, the master locking mechanism begins to lock the house down again. Ariel escapes but discovers that Paul
