The sequel to Escape to Witch Mountain finds Tony Malone (Ike Eisenmann) and his sister, Tia (Kim Richards), in the evil clutches of scheming, money-mad Letha Wedge (played by the inimitable Bette Davis) and her partner, Dr. Victor Gannon (Christopher Lee). The gloomy stone castle where Lee and Davis conduct mind-control experiments on Tony is called “Wolf House” and looms in the Hollywood Hills overlooking L.A. It was built by L. Milton Wolf in the 1920s and boasts 13 rooms on four floors.
