The plot of the story is that Alex Rider has to go to Sayle Enterprises and see if there is anything suspicious. The only reason that they are suspicious is because his uncle found out something and got killed. To get into the factory he had to kidnap a kid who won a contest to be the first kid to use a Stormbreaker. After they kidnapped him, they sent Alex Rider to be him. He had to learn all about him just to make sure that he doesn't get caught. When he arrived they put him into a room and got him started on the StormBreaker. It started instantly and the graphics were amazing. Also, it was very fun to do homework and the time passed so quickly when you are on it. One day he snuck out of bed and went outside. He saw a huge submarine with a bunch of soldiers and boxes being put into a car. One soldier dropped a box and said sorry to the boss but got shot instantly by Yassen Gregorich, a contract killer. While he tried to escape without blowing his cover, two dirt bikes with soldiers riding on it came after him. He tried to run but they got closer and closer. He ran into the forest so it was harder for them to drive. One soldier crashed and Alex Rider took the bike and drove all the way back to the factory. When he got back, Mr. Sayle noticed that he was missing and took him prisoner. They took him on a plane to England while Mr, Sayle is giving a speech about his computers. Quietly, he escaped and put a gun to the pilot's head. He told the pilot to go to where Mr. Sayle was giving his speech. When the plane was over Mr. Sayle, he jumped off the plane with a skydiving suit and shot Mr. Sayle in the hand. This prevented the mouse from activating the Storm Breakers. If the Storm Breakers were activated then it would release a gas that would kill everyone in all the British schools. Once again Alex has saved the day.
