A spinoff of the long-running British series Doctor Who, it centers on the robot dog known as "K-9" (or, more officially, "K9 Mark IV"), a former companion of the Doctor who joins forces with a group of teenagers in "the near-future London" to defend the Earth from worldly and otherworldly threats. The series costars Philippa Coulthard, Keegan Joyce, and Daniel Webber. John Leeson, who first voiced the character of K-9 in 1977, returned to the role for this series.

Siren Of Ceres (Season 1, Episode 5)
Jorjie's mother sends her off to a private school after she witnesses a CCPC robot harassing a protestor and impulsively throws a rock at it. Some of the students have undergone a significant personality change, which one of Jorjie's fellow students suspects is linked to the bracelets that all of the changed girls now wear. The bracelets contain a mind-controlling substance known as Cerulium, which K-9 identifies as being the substance that ultimately destroyed the free will and the civilization of the planet Ceres. At school, Jorjie gives in to peer pressure and accepts a bracelet, placing her under mind control as well. It's up to K-9 and his friends to free the girls and destroy the bracelets before the substance is used to enslave all of London.

Curse Of Anubis (Season 1, Episode 10)
K9 meets the Anubians, an alien race he once helped in his long-forgotten past. Although they were peaceful at that time, they have since become aggressive and warlike, using mind-control technology to subdue their enemies. To distract K-9, they worship him as a God, while other Anubians hypnotize Gryefen, Jorjie, and Stark.
