故事讲述31岁的OL（Office Lady—女职员），神崎岛子（观月亚里沙饰）在「东庆商事」里工作了9年， 一直在总务部工作。她责任心强、工作能力强、很受上司的器重， 人称「MISS 总务」。
为了削减经费， 「东庆商事」决定采用  “outsourcing”的方针。管理层决定将总务部的部份业务以外发的形式交给中国公司，这对职员们来说无疑是一大打击。面对工作将被取代的危机，职员们对派来的3名研习生（胡兵、唐加思、陈怡饰）及他们的经理人（阿部贞夫饰）均抱存排斥之心。更糟的是岛子被上司派为研习生们的导师，岛子心想教导他们，岂不是教晓他们如何夺取自己的工作！？在这种想法的影响以及语言和文化的隔阂下，岛子和其他总务部的员工们与研习生们及他们的经理人阿部几乎每天发生冲突。
不同的国家，因为有着不同的文化差异而容易引起误会、误解及冲突。日本人在拒绝别人时，不会直接说出来，会委婉拒绝。例如：日本人说「要解决这个问题，真的很困难」。听到这句话中国人就会以为：「只是困难而已，不是没有可能」，但是按日本人的常识来说，这句话背后的意思就是，「不可能」。本剧就是抓住这种心态，将中国人在日本公司工作而给日本职员带来怎样的文化冲击，同时也可以令中国的观众多了解一下日本人的想法。中日两国的员工在一起工作的过程中，一起共患难，令岛子及部门的其它日本人明白到中国研习生的努力及他们的优秀之处，由不甘到佩服，逐渐放下成见。并思考真正的敌人到底是中国人，还是他们自己？通过此剧，中国的观众们可以了解日本人如何看待中国人，还有一般中国人对日本人的看法。对促进中日两国的文化交流有着一定的作用，这也是本剧的一个看点。
