When Samantha LeBon (Lysette Anthony) hatches a scheme to spend a romantic Christmas with her new employee -- the unsuspecting, blithesome James (John Travolta) -- his wife (Kirstie Alley), their kids and their two dogs, Rocks and Daphne, must rescue him before he makes a terrible mistake. The voices of Danny DeVito and Diane Keaton go to the dogs, while Tabitha Lupien, David Gallagher and Olympia Dukakis co-star.
