A teacher falls in love with a student, and deals with the reactions of the people around her.

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 is a stray who has nonetheless worked his way into the hearts of a number of the townspeople, who give him food and attention whenever he stops by. His particular favorites are a pair of children who feed and play with him against the wishes of their parents. When the children are kidnapped, however, the parents and the police are at a loss to find them. Only Benji can track them down, but will he be in time? If he can save the day, he may just find the permanent home he's been longing for.
