He completes it but when he is on his way to school he comes across a video game designer. Kevin had given him his assignment of his game and Larry Wolf steals it and which leads Kevin up to summer school. Kevin sneaks out when his dad is away and travels to San Francisco to talk to Larry Wolf. And that leads to a big, huge adventure.
