Joe Johnston's fantasy comedy stars Rick Moranis as Wayne Szalinski, a inventor whose electromagnetic shrinking machine actually works. Unfortunately, it works on his children and their friends, who end up miniscule and stranded in the back yard, a place of infinite danger where insects and lawnmowers become life threatening menaces. As they battle to make their way indoors to get back to normal size, they befriend an ant and fly on a bee in some of the film's dazzling special effects. Once safely indoors, however, they end up in Wayne's breakfast cereal.
