The Rats have gone, and it is time for Mrs. Frisby to move to her summer home with her children. All seems well, but she still thinks of the Rats, Johnathan, and their connection to her children. Will life be different now? How?
The men inquiring about the Rats arrive at the Fitzgibbons' farm. Mrs. Frisby, too worried not to watch, is perched in a tree to see how the final plan at the farm plays out. Will the Rats escape to Thorn Valley? Will the doctor believe he's found just an ordinary rat hole?
Mrs. Frisby's home has been moved successfully, and her children are all safe. Now, the Rats turn their attention to the news about the men coming to the Fitzgibbon's farm. Can the execute a plan that allows them to escape to Thorn Valley in time?
Mrs. Frisby knows she must escape from the bird cage. Even if the Rats are unable to move her home tonight, she must escape to warn them. But can she? The door to the cage is heavy, and the bars are slippery. Will she be able to escape? Will the plan to move her home continue? Will she be able to warn the Rats?
Mrs. Frisby has been captured. Now, as she hangs in a bird cage, as worried as she has ever been, she hears another story. Now, she is worried even more, but not for her own family this time. She is worried for the Rats.
Mrs. Frisby's questions about the Rats and their connection to Johnathan Frisby have been answered and now it is time to put tonight's plan into action. She is nervous about delivering the sleeping draught to Dragon's bowl. Will she be successful? Can the plan to move her home carry on?
Nicodemus's story continues with what the Rats did with the discovery of all the tools and toys in the Toy Tinker's truck. The story of how the Rats created the life they live becomes more apparent, and it is finally revealed what the Plan is, why it has taken so long, and why the Rats feel it is necessary.
Thus far, Nicodemus has told Mrs. Frisby about how lucky it was for them to find the Boniface Estate, but she already knows that they didn't stay there long. How did they come to the Fitzgibbon's farm? And how did they develop such a sophisticated tunnel system as rats? What other stroke of luck befell them?
Nicodemus's story is a long one. So long, in fact, Mrs. Frisby has to return to the children to feed them lunch. Upon her return, Justin takes her through the Main Hall in the Rat's home. Here, she begins to really understand what the Plan is.
The Rats are finally free from the laboratory. Now what? Where will they go? Can they live as they did before they were captured and studied at NIMH? Are they even the same rats? How will they survive now that they are free?
Now that some of the Rats have gone exploring, how will they use their knowledge of the NIMH building to escape? Will they be successful before Dr. Shultz discovers how intelligent they've grown?
Nicodemus continues his story about his time at NIMH. Learning to read was supposed to be part of Dr. Shultz's study. But how will the Rats use this skill for their own benefit?
Now that we know that NIMH is some kind of laboratory, what are they using the rats for? Nicodemus tells us about one of the tests he went through many times at NIMH.
Nicodemus continues the story of how they became the Rats of NIMH. Now they are in the lab and we get a glimpse of what life was like for them there.
Mrs. Frisby just heard how Mr. Frisby died. Now, the mystery surrounding his connection to the rats is even more pressing on her. In this Chapter, Nicodemus begins the story of how the rats on Mr. Fitsgibbon's farm became the Rats of NIMH.
Mrs. Frisby is getting a clearer picture of what life is like for the Rats in the rose bush. But will they still be able to help her?
While waiting for Nicodemus to return to the library, Mrs. Frisby encounters a young child who provides her a closer look at the way of life of the Rats, and perhaps an idea of what the "Plan" is.
Mrs. Frisby is about to enter the Rats home. What will she find? Will they be able to help her?
Mrs. Frisby is at the entrance of the Rats' home. Will they let her in? What will she find?
In the previous chapter, Mrs. Frisby visits the owl who tells her to "Go to the Rats." She returns home, not sure what that means. In this chapter, Mrs. Frisby travels to the rosebush on Mr. Fitsgibbon's farm, where everyone knows the rats live.
We read the first seven chapters in class. This is where we left off. Mrs. Frisby is at the owl's hollow in the forest asking him to help her solve the problem of Moving Day coming in five days. Timothy is still too weak to move. He will surely die. Jeremy the crow flew her there to ask the owl because that is where all the other birds go when they have a problem that they do not know how to solve.
