Trey hides behind a pot and a kid sees him and tells him to stay hidden and "liber". He goes inside and meets, Mrs. Talbot. She doesn't believe Trey wants to help her. Later, they turn on the Tv and head of the Population Police , Aldous Krakenaur has taken over the government.
Mrs. Talbot leaves Trey and Trey hides out in a cabinet eating. The power goes out. When, Trey looked out the window later, he sees what he hopes are Luke and Smits. After Trey goes outside and hides behind a bush, he finds out the 2 kids are Smits and Mark after Mark punches him several times. They make a plan to rescue Luke and the others after the get food and the papers from Mr. Talbots. They get ready to leave. Trey sleeps under the truck.
Trey and Mark leave for the Grants house and meet with Hobart. He reveals everything is shut down in the town. They go their separate ways but agree to mention nothing. They get to the Grants house, the new population police headquarters, and see Population Police guards putting barbed fences up. They also see kids lined up to be population guards, which Mark finds out, to get food. Mark gets electrocuted when he passes through. Guards catch him while Trey hides.
Luke decides to join the line to become a Population Police guard to save Mark. He gets a uniform and goes to the bathroom and goes through the air duct on the ceiling that goes throughout the house. He passes Aldous Krakenaur, the head of the Population Police. He crawls through the ducts to the basement where Mark is and a guard comes down, as he leaves Trey tells Mark to yell "liber". The guard comes down and they learn he is working against the Population Police and they work out a plan to go to Nezeree to get all of their friends and a extra prisoner.
While driving to Nezeree to get the "prisoners" a mob attacks the truck and knocks it over, Trey tricks the mob and gets it back upright. Mark's cage broke in the fall, and so did his leg. They get to Nezeree and Trey's "attitude to the Population Police", makes the warden like him. He gets a new uniform, since its ripped up, breakfast, and a hot shower from the warden. Trey sees on the TV that the Population Police caught Sabine and his son, the people that were working undercover. Trey rips the warden's direct telephone line to the Population Police in fear of being caught. Mark and Nedley, a undercover helper for the population police slice all the tires of their trucks. They all get away.
Trey shows Mr. Talbot the papers he got from his house, and Mr. Talbot reveals they are actually third children's secret codes that if the government got a hold of, so many kids would be dead. Mr. Talbot wants to burn them, but Trey saves the papers. Trey doesn't want them to forget who they are. They all reveal their true names and Trey gives a speech and wants to fight against the population police with the help of others.
