Return from Witch Mountain is the sequel to the cult classic teenage sci-fi film Escape to Witch Mountain. The sequel again centers on Tia (Kim Richards) and her brother Tony (Ike Eisenmann), kids with supernatural powers that allow them to communicate and move objects with the power of their minds.

While in Los Angeles for a visit, Tony uses his powers to prevent an accident, and a ruthless scientist, Dr. Victor Gannon (Christopher Lee), who’s looking to control the world, finds out and kidnaps Tony. Gannon implants a device near Tony’s brain, enabling him to control Tony’s will. His sister Tia, along with a group of kids, spring into action in order to free Tony and save Earth.
