Hacker decides that he can force cybersites to surrender by annoying them big time. He broadcasts his loud and obnoxious voice across the vastness of cyberspace from a massive statue shaped like the arrogant Hacker himself. The kids and Digit are sent by Motherboard to the Northern Frontier, where they carry out a Mission Impossible style scheme to silence the statue and disable Hacker's intimidation. Using their skills at measuring length, the kids make their way up through the inside of the booby-trapped statue to Hacker's pointy chin and big mouth. But can they shut him up before Hacker shuts them down? The Big Idea: To measure length and communicate your results easily and precisely, identify a system of units based on a single standard length that everyone using it agrees on.
