In this family adventure, a young boy sees a strange train stop outside his window on Christmas Eve. When he goes to investigate, he's invited on board by the mysterious conductor (Tom Hanks), who reveals that the train is full of children heading to visit Santa at the North Pole. Along the way, the children learn about the real meaning of Christmas and the power of believing. The movie is based on the children's book The Polar Express by Chris Van Allsburg.
