Bart is a city dog who lives in a huge apartment building in Greenwich Village. His owner is Max, the nicest owner in the world. Bart longs to see the sights of the city on his own, especially at Christmastime, sans leash. Unfortunately, Max always forces Bart to stay on a leash (for his own good). One day in December, when Max is carrying an oversized Christmas Tree into the apartment, Bart goes for it and dashes out into the big city, where he dances with the Rockettes at Radio City Music Hall, ice skates in Rockefeller Center, takes a trip on the Staten Island Ferry, then heads back to his warm home in Greenwich Village, and snuggles with his owner, awaiting Santa´s arrival.
