In this animated feature, the few humans who have survived the devastation of the earth by pollution live underground in something called the Rat Dictatorship, ruled over by a president who electronically brainwashes misbehaving members of the population. In the story, a family, led by a grandmother who has had a vision of paradise, seeks to escape their underground prison. Through their persistence and trickery, the clever family (consisting of a drunken uncle, a granny and a brother and sister) eventually win free.
