The long lost Totally Rad Ring of Radopolis has been found...and is soon swiped by Hacker. This powerful crown will grant the wearer his heart's desire, and Hacker is a cyborg who wants it all. From a new head of gorgeous hair to total cyberdomination, Hacker enjoys wreaking havoc with his new Ring. While racing to reclaim the Ring, the CyberSquad meets a mysterious teenborg named Slider. He seems nice, but whose side is he really on? The kids must all work together to get the Ring back from Hacker and put it inside the Circle of Supreme Safety before Hacker destroys Motherboard once and for all. But the Ring must be placed in the exact center of the circle -- only then will it be safe from those who wish to use its power to harm others.
