He’s going to find out who’s naughty or nice?…Not if they’ve got anything to do with it!

Snow is on the ground and the magic of Christmas is in the air, but when Aisling and Joe, two badly-behaved yet good-natured children, antagonise their tough new babysitter she writes to Santa asking him to put them on the naughty kids’ list. Determined not to be denied their Christmas presents, Aisling and Joe seek the help of the toughest boy in school. He gets presents every year no matter how badly he behaves so he must have some good ideas on how to get their names off the list. He does have some ideas, but unfortunately, they’re not that good.

They end up stealing what they think is Santa’s bad kids’ list; if Santa doesn’t have the list, he’ll have to give presents to everyone, no matter how they’ve behaved during the year.

But when they find out what they’ve actually taken is the list of all the gifts to be delivered around the world they decide they have to return it. After all, the last thing they want to do is ruin Christmas for everyone. And if doing the right thing for once means they’ll get into trouble, then that’s just what they’re going to have to do.

The children face a race against time to return the list to Mr Claus, only to find that someone is trying to stop them. Someone who hates Christmas and wants everyone to be just as miserable as he is.. Can they save Christmas in time?
