This is the best film I've ever seen about time travel.Tom is a young lad who's mom has a new fellow.Tom falls through the back of a fireplace in a burned out farm house with a dog.They end up in the dog's time.That is where Tom meets May a girl of his age.Tess is May's dog,and she went looking for someone to help May.This film is way to good to know much more about it.You have two kids by the end that have helped each other.Don't miss this fine film.
