When Digit’s systems go wonky, Motherboard sends him to the caves that house the synchronizer: the beautiful crystal that keeps all borgs correctly timed. Before he can be put back in sync, he gets a glitch and tosses his crystal synchrometer into a tunnel. Then, he flies off the wrong way down into a deep, dark chasm. Called in to help, Jackie, Matt, and Inez meet Jules, the cave's timid guard. They team up to find the synchrometer and Digit. Part of the "Cyberchase" series.
