The Bannister familys new addition, Zeus (voiced by Mario Lopez of TVs SAVED BY THE BELL), the yellow Labrador, appears to be less than the dependable guard dog the family needs. However, when two burglars set out to break into the Bannisters home while theyre away for Christmas, Zeus seizes the chance to be a hero, proving every dog - even this one - has his day. Dean Cain (TVs LOIS and CLARK), Gary Valentine (TVs THE KING OF QUEENS), Elisa Donovan (CLUELESS, TVs SABRINA THE TEENAGE WITCH), Mindy Sterling (AUSTIN POWERS), and Adrienne Barbeau (MAUDE, CARINVALE) also lend their voices in this heart-warming holiday movie.
