A teen-age girl, just starting jr-high, living in a modern "corporate" community is accidentally contaminated by a secret chemical product of The Plant. She acquires mysterious abilities that allow her to change her shape, move objects remotely, and "zap" people and objects with small electrical charges. The owners of The Plant continuously seek to find out which of the local kids has been contaminated so they can experiment on her, but their employees are less than competent and the search is comedic and futile.
