A snobbish investor and a wily street con-artist find their positions reversed as part of a bet by two callous millionaires.

While on a publicity tour in Switzerland, Benji, Cindy Smith, and Patsy Garrett convince Kris Kringle that his place on Christmas Eve is delivering presents to all "his" families all over the world.

Benji gets lost after a flight overseas and becomes a stray in Athens, Greece. He then tries everyday to reunite with his family while mysterious people pursue him, in a race to get a code which was secretly tattooed on his paw at the airport. But who are the bad guys and who are the agents that can be trusted? Will Benji and his kids and their nanny ever get to enjoy their vacation?

Benji has become stranded on a remote island after a boating accident. He finds himself struggling to survive in the wilderness, avoiding close encounters with a wolf, a bear, and a territorial female cougar with her cub.

Browning is a PI with a bad cold, who's sent to investigate a case by a mysterious client. He stumbles across the body of a young woman and is stabbed to death, and when he wakes up in heaven, they tell him he's "marginal material," and they can only decide on his final destination through one last assignment: to go back and solve his own murder. As a dog. A cute fluffy little dog (Benji). Undaunted, Browning begins to investigate the case as best he can around his canine disabilities (dialing the phone presents a special challenge) to solve the murders, save the girl, and see justice done.

As the lovable mutt prepares to perform the first SCUBA dive by an animal, a villain attempts to prevent it.
