BIG BROTHER IS WATCHING -- BUT SOMETIMES CAMERAS DON'T TELL THE WHOLE TRUTH!

College student Jake Martins is in trouble, and the Hardys volunteer to help out. Securitech, the firm where Jake works, is wiring the city to catch wrongdoers. But to pass one of his courses, Jake may have to reveal some secret information, and now he's in a bind.

When security cameras keep going off-line and more criminal activity gets city officials up in arms, Jake is the main suspect. Someone's cracking the codes in the system -- and it's up to the Hardys to get the criminals in focus!
