In 2025, the Internet and its virtual reality network have to be policed by the Net Force to prevent cyber-terrorists from sabotaging it.
They are assisted by the Net Force Explorers, a young people's auxiliary for computer experts who have completed a rigorous training program.
[1][2][3] The explorers include Maj (Madeline) Green, David Gray, Matt Hunter, Mark Gridley, Leif Anderson, Andy Moore, Megan O'Malley, Catie, and Charlie Davis, and are led by former Marine commander Captain James Winters.
The young people solve cyber-crimes and defeat international terrorists while creating virtual worlds and playing high-tech computer games.
