Suee and the Zero Detective Club are back and ready to unravel some mysteries! However, other than a bunch of missing cat cases, there really isn't too much to solve... until Smartie, Suee's kid-nemesis from her old school, goes missing leaving only one clue: Central City. Nemesis or not, it's up to Suee and the rest of the Zero Detective Club members to find her. But Smartie's disappearance isn't the only weird thing going on in this part of town. There's an army of workers in white uniforms installing strange devices, and all the adults have started acting bizarre and ignoring their kids. With all these odd occurrences, it's up to the Zero Detective Club of Outskirtsville to find out what's going on!
