Brian Foster (Wesley Eure) is a young inventor who creates a mechanical dog as part of a home protection system. When he falls out of favor with his boss Ralph Norton (Conrad Bain), the boss' pretty daughter Casey (Valerie Bertinelli) uses her pull to save the company and Brian's job. Mr. Gibbs (Jim Backus) is the rival company president who covets the mechanical mutt. He sends double agent Ken Sharp (Larry Bishop) to do his bidding, and Ken in turn hires a pair of bumbling crooks (Red Buttons), (Chuck McCann) to steal the dog. The real star of this family-oriented comedy is the mechanical dog Chomps. ~ Dan Pavlides, Rovi
