Justin has his sights set on winning the science fair with his newest creation – a remote controlled life-sized robot named Largon. Justin not only impresses his best friend, Ranger, with his new robot, but the sweet-talking Largon soon steals the affections of Justin’s girlfriend and her friend Nicole. The girls swoon over Largon and, to Ranger’s dismay, Nicole asks Largon to the school dance! And to make matters worse, three school troublemakers devise a plan to steal Largon and enter him as their exhibit in the science fair.
