From the creator of 'Thunderbinds' and 'Captain Scarlet' and the 'Mysterons' comes 'Terrahawks', the eighties puppet science fiction series which relaunched Gerry Anderson's career for a new decade and a new legion of fans. In the year 2020, Earth is menaced by the android Zelda, Imperial Queen of Planet Guk, and her hideous 'family'. They are bent on destroying all humanoid life in the galaxy, and Earth is their next target! Zelda's 'son'Yung-Star fancies himself as an evil genius, but it is soon clear that he isn't up to the job, while her 'sister' Cy-Star does not care about the invasion of Earth, so long as she's wearing the right outfit for the occasion. Now they are joined by Cy-Star's son It-Star, an evil genius with dual personalities - a charming little girl and a horrid little boy. In their Mars-based fleet of ships, Zelda carries monsters collected from throughout the universe held in suspended animation, ready to be inflicted upon the unsuspecting people of Planet Earth. Terrahawks is led by the clone Dr 'Tiger' Ninestein, assisted by Mary Falconer, Hiro, Hawkeye, and the international pop star Kate Kestrel, plus the spherical bouncing robot Zeroids. In their secret South American base Hawknest, with the world's most advanced fighting machines at their disposal, the Terrahawks wage a never ending war against the invaders from Mars.
1. First Strike Earth's authorities have had enough of the stalemate between Zelda and the Terrahawks and authorise a military strike on Mars by Space Marines. Tiger fears the plan is doomed to failure and mistrusts General Cord, with his gung-ho attitude and ever-present belt full of live grenades. 2. Terrattomb Zelda has managed to smuggle a bomb into Hawknest. How has she done this when she doesn't know the location of the secret base? Tiger needs answers fast, or Hawknest will become the Terrahawks' tomb. 3. Doppelganger Itstar has developed a fiendish new invention: a method of producing exact duplicates of people. But how exactly will producing a duplicate Yungstar help in the invasion of Earth, and why has his double turned up in a museum. 4. Cry UFO In an episode originally designed to be a pilot for a spin-off series, Kate Kestrel's musical director Stew Dapples sees a huge UFO, but nobody ever takes the daffy Stew seriously, least of all the local police in Badwater County.
