A widowed field mouse must move her family to safety before the farmer's plow destroys their home. Her sick son requires medicine, and her only hope lies in seeking help from the mysterious rats of NIMH, a highly intelligent group living under a rosebush. They possess a secret technology and a connection to a past laboratory experiment that gave them heightened intelligence.
