The misadventures of a boy genius and his annoying sister.

Dexter is a Boy Genius Who has a secret lab in his room his Mom and Dad don't know about it, but his older sister Dee Dee Does and they go on wacky (yet Sci-fi) Capers—hailey

If you ever meet Dexter, you'd probably notice a few things about him: he speaks with an Eastern-European accent, wears a labcoat, and happens to be a boy-genius with an amazing laboratory in his bedroom! The show follows Dexter's adventures, in and out of the lab, as he copes with his crazy parents (who are completely oblivous to their son's high IQ and laboratory), fights with his sister DeeDee (who sees the lab as her own playground and never wants to leave), and battles his arch-nemesis Mandark (who also possess an impressive laboratory).—Lex

While most children his age would rather be outside playing than at school, Dexter is secretly busy in his own highly advanced laboratory working on his latest scientific invention. His parents don't know what he's up to in his room all the time, but his older sister Dee Dee likes to sneak her way in and push Dexter's buttonsm - literally and metaphorically.—J-pm
