It is the CyberSquad’s most ingenious plan ever. If they can insert a new memory chip into Hacker, they can turn him from evil to good. Once he has been shrunk and is inside Hacker, Matt’s mission goes like clockwork until a force field is activated. All seems lost until Digit remembers a robot that Dr. Marbles made that can break through any force field. They can shrink it down and send it in to help Matt. Part of the "Cyberchase" series.
