Genius United Robotronics cybernetics engineer Ted Lawson, brings home for assembly and long-term field beta testing Vicki, or V.I.C.I. (Voice Input Child Identicant): a secretly constructed robotic domestic aide in the form of a 10-year-old girl, to whom housewife Joan takes a shine while 10-year-old son Jamie instantly takes advantage of Vicki as a maid to clean his room and do his homework.
Nosy neighbors, the Brindles, invite themselves over for dinner due to a power outage at their house. Naturally, Vicky tickles their curiosity, leading them to ask several questions that the Lawsons have no answers for. Can the Lawsons keep Vicky from blowing the evening - and her cover?
Jamie uses Vicky's new read-and-scan computer program to do his school reports for him. She does such a good job, though, that his teacher wants to move Jamie to the honors class. But when his parents find out, they give him the chance to come clean on his own.
When nosy Mrs. Brindle reports the Lawsons to child services for not having Vicky enrolled in school, the Lawsons rush to forge adoption papers. But their plan gets complicated when a doctor's exam is required - on their robot.
Ms. Fernwald of Child Services forces the Lawsons to hire a tutor for Vicky. But when the tutor gets too excited about Vicky's super memory, Ted gets worried and comes up with an idea for a replacement teacher.
