Could virtual reality be used to explore the galaxy? Dave and his friend Jon think so. When they decode an alien message they discover a three-dimensional environment populated by virtual aliens with an invitation to join the Galactanet. But Dave and Jon can only take up this offer by becoming virtual themselves.

Things get more complicated as a hacker in the employ of a certain Dr. Werner infiltrates Dave's virtual reality system, causing mayhem. Soon Dr. Werner's machinations threaten the very existence of the Galactanet itself. Can Dave and his friends come up with a way to save the galaxy?
