Kate is an ordinary 11-year-old girl. She has a brother, Tom, and a mysterious uncle, Herbert, whom they have never met. But one day, for her birthday, Kate receives an unexpected gift from her uncle: a magical train called "Silver Arrow". And since then, fantastic events have been happening in the lives of Kate and Tom. Because the children go on a journey. And "Silver Arrow" rushes them to the world of adventure. An extraordinary train takes children to distant lands, occasionally stopping at magical railway stations. They get to a place where exotic animals live, which, it turns out, can talk. A place where Kate and Tom had never been, not even in their dreams. Adventures and the unknown await the brother and sister, which excites and beckons. And this journey is an opportunity to save the whole world...
