Lola is very excited for Christmas, but her Christmas is about to be ruined when she mixes Lotta's card for Father Christmas' by accident. When Lola and Charlie find that the door for Christmas on their advent calendar has been lost, they make their own door on the calendar, making their way to the magic elves at the North Pole.

It is the beginning of Autumn term at school, and Lola finds that everything is different. She and Lotta have new sitting places, she has a new teacher, the school smells funny, and the leaves have fallen off of her favourite tree. Meanwhile, Charlie and Marv create a time capsule for the Autumn Fair.
