Mrs. Frisby and the Rats of NIMH

With nowhere else to turn, a field mouse asks the clever escaped lab rats living under the rosebush to help save her son, who lies in the path of the farmer's tractor, too ill to be moved.

Mrs. Frisby, a widowed mouse with four small children, is faced with a terrible problem. She must move her family to their summer quarters immediately, or face almost certain death. But her youngest son, Timothy, lies ill with pneumonia and must not be moved. Fortunately, she encounters the rats of NIMH, an extraordinary breed of highly intelligent creatures, who come up with a brilliant solution to her dilemma. And Mrs. Frisby in turn renders them a great service.
