Drake uses a strange alien substance on a group of school children in an experiment to gain control of the population. Jorjie stumbles across the plan after she is seen assaulting a CCPC, and Drake suggests to June that she send Jorjie to a Private Academy to deal with her lack of discipline. Jorjie herself succumbs under the alien control and K-9 and Starkey have to find and destroy the control devices.
