Mr Peterson (David Tennant) is an anxious supply teacher who takes a job at an underachieving primary school, St Bernadette's. He struggles to care for both his uninspired pupils, and his heavily pregnant wife (Joanna Page). He lives in the shadow of his overachieving 'golden boy' identical twin brother (also played by David Tennant), who is a teacher at a posh private school, St. Cuthbert's College.[5] The brothers' rivalry intensifies when they both enter their classes into the national 'Sing a Song for Christmas' competition. Mr Shakespeare (Jason Watkins) and Oakmore are back as well, hoping to win the competition. Mr Peterson ends up taking his class (as well as a donkey) on an unauthorised school trip to the competition's location at Christmas Castle, but they become lost, and embark on an epic trip across the country, travelling by any means necessary. Mr Peterson must use all his resources and do whatever he can to guide his pupils to safety a【ZiYuanTun.Com】nd reach Christmas Castle, if they are to win the competition. 译文(2): 彼得森先生(大卫 · 坦南特)是一位焦虑的代课老师，他在一所成绩不佳的小学——圣伯纳黛特学校找到了一份工{资源屯-ziyuantun.com}。他努力照顾他那些没有灵感的学生和他怀孕的妻子(乔安娜 · 佩奇)。他的同卵双胞胎兄弟(也由 David Tennant 扮演)是圣卡斯伯特学院一所豪华私立学校的老师。[5]当两兄弟都进入全国“圣诞歌唱大赛”时，他们之间的竞争更加激烈了。莎士比亚先生(杰森沃特金斯)和奥克莫尔也回来了，希望能赢得比赛。彼得森先生最终带着他的班级(还有一头驴)进行了一次未经授权的学校旅行，前往比赛地点圣诞城堡，但是他们迷路了，开始了一次史诗般的全国旅行，不惜一切代价。彼得森先生必须使用他所有的资源，并尽一切可能引导他的学生到达安全的圣诞城堡，如果他们要赢得竞争。
