In the beginning of this book, a red blinking chip which was the source of energy for the Homework Machine, goes missing. The D-Squad soon finds out that Ronnie Teotwawki has the chip, and could do some bad things with it. So, Brenton, Judy, Sam, and Kelsey plan to go to his house and steal the chip from him. Sam decides to try and steal it since he was the only one with enough nerves to try and get the chip back. When Sam is at Ronnie's house, he finds an unlocked window but when he gets in, there is an alarm and a loud barking noise from a dog, so Sam gets scared and runs back home. Ronnie finds out how powerful the chip is and makes his own homework machine for only himself. Brenton also starts to get emails from Richard Milner, who Brenton bought the computer chip from. He was emailing Brenton about the chip and if he found it, every day. Soon, it is Christmas time and Ronnie gets a GPS for Christmas. In school, Mr. Murphy teaches about the Grand Canyon and there was a newspaper article about a person who found treasure from long ago in the Grand Canyon, and Ronnie, Judy, Brenton, Kelsey, and Sam were paying attention to Mr. Murphy's lesson, so they decided to look for the treasure of the Grand Canyon. They all went to the library, and the D-Squad met Ronnie there, looking for the newspaper article on the Grand Canyon. Ronnie puts the chip in his GPS to help him find the treasure, and he soon starts to get emails from Milner. Milner and Ronnie team up to find the missing treasure and the D-Squad also goes to find the treasure, but they find themselves together in part of the Grand Canyon. Milner drinks some whiskey as a celebration and gets drunk when they found the treasure, then the D-Squad and Mr. Murphy come and find Ronnie and Milner together near the treasure. Then, Milner gets a sword and tries to attack Mr. Murphy, but he kicks Milner and then Milner falls off a cliff into the Grand Canyon. The police start investigating, but Mr. Murphy doesn't tell the police what happened and Ronnie becomes friends with the D-Squad. They then shoot a rocket off into space with the chip in it to get rid of it, and the chip is gone.
