The villainous Hacker is determined to rule Cyberchase - no matter what it takes. But he never will - at least, not if Jackie, Matt, and Inez have anything to say about it. These three young heroes embark on thrilling adventures - from tackling time in ancient Egyptian tombs to cracking codes in creepy caves - in their quest to foil Hacker's dastardly schemes. In the wacky live action segments that ends each show, tween characters show that math can also save the day in real life.
