This Christmas the children of St. Bernadette’s primary school face their biggest adventure yet as they enter a Christmas flashmob competition to win a trip to New York! The only problem is their new teacher Mr Shepherd has lost his memory and can’t recall anything about Christmas, and even worse – he has no idea where he left Mr Poppy’s beloved donkey. Now the children must remind Mr Shepherd of what Christmas is all about before their Christmas turns into the most disastrous ever.
