The story follows four characters - two mice named Sniff and Scurry, and two little people named Hem and Haw - who search for cheese in a maze. One morning, they discover their usual source of cheese, Cheese Station C, has no cheese. While Sniff and Scurry quickly set off to find new cheese, Hem refuses to accept the change and Haw initially struggles but eventually decides to search the maze for new cheese as well. After facing his fears and changing his beliefs, Haw discovers a large new source of cheese, Cheese Station N, where he is reunited with Sniff and Scurry.
