When he learns that his father has disappeared from Caldecott Preparatory (aka CPU), one of the most prestigious computer and technology schools in the country, eleven-year-old Ty Hansen enrolls in the school and changes his name to Devon Riley in hopes of solving the mystery. Devon finds challenging classes at CPU, a game called VOLT, and clues about his father's disappearance.
While attending classes, Devon befriends Mina Kim, the daughter of a teacher. Together they work on completing new levels of the school's virtual game, VOLT. But something is wrong within the game, and the programming seems to take on a life of its own.
