Ivy is an orphan who has always pretended that she has a grandmother. On Christmas Eve, Ivy is put on a train bound for a children's home where she is to spend Christmas day. But when the train stops, Ivy jumps off, sure that this is where her grandmother lives. And she wishes, very hard, that her grandmother will give her the special Christmas doll she's always wanted.

Meanwhile, a beautiful little Christmas doll called Holly is waiting, arms outstretched, in the window of Mr Blossom's toy shop. As night falls, Ivy comes across the toy shop. She notices Holly straightaway. But the shop is shut. And Ivy has no money anyway. Could it be that if both Holly and Ivy wish hard enough, their dream to be together will come true?
