A family finds themselves on the run from danger both on earth and from outer space in this sci-fi comedy for the family. Joe Yeagher (Terry Kiser) is a plumber from Brooklyn who is placed in the Federal Witness Protection Program after testifying in court against some wise guys from the neighborhood.

Lonely in their new town, Charlie and Dena visit a local pet shop run by Mr. and Mrs. Zimm (Jeff Mitchalski and Jane Morris), where the kids discover a number of strange and wonderful animals for sale. But they soon discover that the Zimms and their critters are all visitors from another planet, and that the humanoid aliens plan to take the Earth children back to their planet and sell them as pets. Can the alien animals and FBI keep Charlie and Dena safe?
