Summer Wars

PG

Koiso is a computer geek and goes to his friend, Natsuki's summer house for the holidays. He meets her family and has a great time. Late at night he is sent a email from a online site named the love machine. It's a long code, he solves it and sends it back to the person. The next day the love machine breaks into the main computer system and messes everything up...transport times, traffic lights, love machine accounts and the satellite connections.

Koiso is blamed for doing it and the only way to clear his name is to stop the hacker. He finds out that one of the family members had actually created the love machine and then sold it to the US military.

To beat the hacker they must beat him in a variety of online games with the game accounts they have created.
