In the chapters 21-27, Nicodemus finihes telling the story of NIMH and their escape. He also tells her about the Toy Tinker and that explains some of the amazing gadgets that the rats own. He also tells her about The Plan to move to Thorn Valley and not live a life of robbery. Then as soon as Nicodemus finishes the story it is time for Mrs. Frisby to put the powder in Dragon's bowl.
So Mrs. Frisby sets off with Justin showing her the way. She enters the house and puts the powder in the bowl. On that one day Billy decides to sit on a stool above the bowl and she gets captured in a colander. Justin becomes very worried for her and her children. Mrs. Frisby though is put in a birdcage of the past bird of the Fitzgibbon's. The Fitzgibbons sat down for dinner with Mrs. Frisby hanging above their heads. That's when she finds out about about the seven dead rats and that the rosebush will be exterminated to kill the rats. Mrs. Frisby begins to panic. She pushes and pulls to get out but then Justin comes and unlatches the lock to set her free. They exit the house at night and Justin tells her about the shrew not letting them move the house. When they arrive at the cinder block Mrs. Frisby explains it to the shrew so they move the house successfully. Then after that, Mrs. Frisby tells Nicodemus about the extermination.
Nicodemus gathers every rat in the colony in the meeting room to explain that they will be leaving for Thorn Valley immediately. Although ten will be staying back in the rosebush but in a regular rat hole. They won't stay and die though they will escape through a secret exit leading to the woods. So the next day when they come the rats are prepared and go to work. The exterminators put the gas pump in the hole and block the first exit. The rats though escape the second exit and nine come out and and one of them goes back in to attempt to save the other, but neither come out. One of them is wobbly and collapses. Mrs. Frisby rushes down from her perch in a tree and Mr. Agesshows up to but he has medicine because the rat took in too much cyanide. The rat was Brutus, but he was okay. They find out that the rat that went back to try to save another was Justin. He is dead but the other rats live in Thorn Valley.
