In a post-apocalyptic earth, where most of humanity lives underground, a group of surface people stumble upon an abandoned lab that was trying to bring life back to the earth's surface, but the place is run over by vicious rats.

A murdered couple return from the beyond to care for their two young children, as well as seek revenge against their killer, accept their children's step parents, and try to prevent their house from being sold.
