The main character of the series is Dexter a boy-genius with thick glasses, who hides a secret laboratory behind a bookcase in his bedroom. This lab is filled with Dexter’s inventions and can only be accessed with passwords or by activating hidden switches on Dexter’s bookshelf. Although Dexter is very intelligent, he often fails his plans because of overexcitement or bad choices. Dexter manages to keep his lab a secret from his parents, but unfortunately not from his hyperactive older sister Dee Dee. Dee Dee finds ways to brake into the laboratory and often plays with Dexter’s inventions in a careless way. Dexter’s nemesis is another boy-genius from his school, nicknamed Mandark. He also possesses his own laboratory, but his schemes are evil and are designed to gain power or destroy Dexter’s inventions, who are better than his. Mandark tries to compensate his failures by stealing Dexter’s plans. Mandark is in love with Dexter’s sister Dee Dee.
