The show consists of a mixture of live action real world sequences interspersed with computer-generated scenes set inside a virtual realm. Zixx is an Intergalactic Network (simplified as the Network) agent who has crash landed onto Earth with her partner Flanngo. As luck would have it, Earth also happens to be a hotbed of activity for the evil Onccalon and the Hargokk Empire. Zixx has no intention of letting him win, so she and Flanngo need to find a way to access the Network and make sure they can get to the next level of the Keep before Onccalon's henchmen do.
