 Inside of your computer is a world you ve only dreamed of. A small system/city known as Mainframe is watched over by a "living on the edge" guardian named as Bob. With the help of the work-a-holic Dot Matrix and her hyper active little bother, Enzo, they protect Mainframe from viruses and games. As their lives grow more chaotic by the nanosecond, Bob becomes a part of their family and makes the city his home. Yet what starts off as casual battles and teasing of the viruses changes into a serious threat that could cost Bob, Dot, Enzo and their friends not only their lives, but Mainframe as well.
