London, late 21st Century. "The Department", using android police, the "CCPC", control the peace and are the defence force against Alien intrusion. Working on Alien Space-Time Manipulator, Professor Gryffen has unwanted visitors to his mansion house, a converted old police station; first a young rebel called Starkey and his new friend Jorjie; then, a group of reptilian aliens.. the Jixen! A strange robot dog follows through the STM and saves the humans under threat by sacrificing himself. However, the boy Starkey triggers a "regeneration" disc and the robot dog renews himself completely ... the new look K9 is born! Darius, Gryffen's assistant, informs the CCPC of Starkey's whereabouts and he is captured and sent to the Department's detention centre. Starkey escapes when a surviving Jixen stalks him. K9 had no memory prior to arrival in the mansion and Gryffen tries to help. Jorjie tells Starkey about Dauntless Prison where the Department are holding aliens as prisoners for sinister experiments!
