When he decides to ruin the class’s annual Christmas trip though, his friends get angry and freeze him out. His only hope of making everything right again now lies in a competition where the class has to win the perfect VIP Christmas trip to a castle. Everyone tries their best to make it happen, until an anonymous elf appears.

Unfortunately the mysterious elf will through blackmail, mockery and lies prevent Magnus and the class from winning the competition. The hunt begins to reveal the villain, so that the children can experience the perfect ‘Class’ Christmas together.
