The story is an allegory about two mice (Sniff and Scurry) and two little people (Hem and Haw) who search for cheese in a maze every day. When the cheese is no longer available at their usual station, the mice quickly adapt and find new cheese while the little people struggle to accept the change. Haw eventually realizes they must change their approach to find new cheese. He convinces Hem, and together they learn to embrace change rather than fearing it.
