Red-haired 11-year-old twin siblings, Rachel (Kirsty Wilkinson) and Theo (Lance Warren) Matheson are on a summer holiday visiting their aunt and uncle (Glynis McNicoll and Noel Trevarthen) in Auckland (New Zealand) when they meet a mysterious man called Mr Jones who helped find them when they got lost in the woods eight years earlier.
Mr Jones (Roy Leywood) turns out to be an alien fighter from a distant planet who wants their help in fighting an alien family of giant slugs – led by a Mr Wilberforce (William Johnson) – who have arrived on Earth and taken on human form with plans for world domination and the destruction of our planet.
Rachel and Theo have psychic abilities which gradually increase in effectiveness and strength.
Based on a novel by Maurice Gee,Β Under The MountainΒ was filmed on location in and around Auckland and made extensive use of surrounding mountains, volcanic lakes and panoramic views (long before the Lord of The RingsΒ franchise discovered the picturesque nature of NZ).
The series was sold to the US where it aired on Nickelodeon in 1983 under their The Third Eye banner.
A movie-length remake starring Sam Neill was produced in 2009.
