Teenager Tom Majors has discovered that the remote control scanner used for an online game is actually a portal that transports his consciousness to an alternate world called Chaotic. In Chaotic, advanced players can make the characters on their game cards come to life. When these players engage in battle, they actually become the character or monster they are playing. The rest of the population of Chaotic can watch the match-ups via monitors. As the Tom and his friend play, they discover the codes of additional creatures, locations and items in Perim. These can be added to their gaming "decks" through the use of their scanners.
