Erstwhile inventor Prof. Wayne Szalinski (Rick Moranis) has been experimenting with an electromagnetic shrinking machine. He leaves the device unattended in his attic; shortly afterward, it is accidentally activated. Alas, the demon machine is aimed at his children, as well as the son of neighbor Russ Thompson (Matt Frewer). The kids, shrunk to 1/4-inch height, are tossed into the trash bin by the unwitting Szalinski. For the rest of the film, our teeny-tiny protagonists attempt to gain their parents' attention -- and to survive the wilds of the backyard, where all sorts of dangers, from bumblebees to lawnmowers, threaten their well-being.
