When Abbey School gets a connection to the information superhighway, computer nerd and video game freak Josh Allan and his bookworm best friend, Tamsyn Smith, sign up to write a report on the new connection. As they begin their research on electronic mail, they get a message from a mysterious Internet user, ZMASTER, welcoming them to the Internet. Tamsyn puts up with ZMASTER's silly notes, but when she receives a message calling for help, it's up to her and Josh to find and save ZMASTER before time runs out. Internet Detectives: Net Bandits is based on the book of the same title by the author Michael Coleman.
